ITEM 5.  Other Events

     On November 26, 1997,  Norwest  Asset  Securities  Corporation,  a Delaware
corporation (the "Registrant"),  sold Mortgage Pass-Through Certificates, Series
1997-19, Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-6, Class
A-7, Class A-8,  Class A-9, Class A-R, Class A-LR,  Class M, Class B-1 and Class
B-2 (the "Offered Certificates"), having an aggregate original principal balance
of $247,638,000.00.  The Offered  Certificates were issued pursuant to a Pooling
and Servicing  Agreement,  dated as of November 26, 1997,  among the Registrant,
Norwest Bank Minnesota,  National  Association,  as master servicer (the "Master
Servicer"  or "Norwest  Bank"),  United  States  Trust  Company of New York,  as
trustee,   and  First  Union   National  Bank,  as  trust   administrator   (the
"Agreement"),  a  copy  of  which  is  filed  as  an  exhibit  hereto.  Mortgage
Pass-Through  Certificates,  Series 1997-19,  Class A-PO Certificates (having an
initial principal balance of $468,046.53),  Class A-WIO Certificates  (having no
principal  balance) and Class B-3, Class B-4 and Class B-5 Certificates  (having
an aggregate initial  principal balance of $2,127,978.50)  (the "Private Class B
Certificates"  and,  together  with the Class  A-PO  Certificates,  Class  A-WIO
Certificates and the Offered Certificates, the "Certificates"), were also issued
pursuant to the Agreement.

     As of the date of initial issuance,  the Offered Certificates  evidenced an
approximate  98.96%  undivided  interest in a trust fund (the  "Trust  Estate"),
consisting principally of a pool of fixed interest rate,  conventional,  monthly
pay, fully-amortizing, one-to four-family residential first mortgage loans which
may include loans secured by shares issued by cooperative housing  corporations.
The  remaining  undivided  interests  in the Trust  Estate are  evidenced by the
Private  Class B  Certificates,  distributions  on  which  are  subordinated  to
distributions  on the Offered  Certificates,  and the Class A-WIO and Class A-PO
Certificates.

     Interest  on  the  Offered   Certificates   will  be  distributed  on  each
Distribution  Date (as  defined  in the  Agreement).  Monthly  distributions  in
reduction of the principal balance of the Offered Certificates will be allocated
to the Offered  Certificates  in accordance with the priorities set forth in the
Agreement.  Distributions  of interest and in reduction of principal  balance on
any  Distribution  Date will be made to the  extent  that the Pool  Distribution
Amount is sufficient therefor.

     An  election  will be made to treat the  Trust  Estate  as two  REMICs  for
federal  income tax purposes (the  "Upper-Tier  REMIC" and  "Lower-Tier  REMIC,"
respectively).  The Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class
A-6, Class A-7, Class A-8,  Class A-9, Class A-WIO,  Class A-PO,  Class M, Class
B-1, Class B-2, Class B-3, Class B-4 and Class B-5 Certificates  will be treated
as "regular  interests" in the Upper-Tier REMIC and the Class A-R and Class A-LR
Certificate will be treated as the "residual  interests" in the Upper-Tier REMIC
and Lower-Tier REMIC, respectively.

before the Cut-Off Date), (b) the Insurance Policies, (c) the obligations of the
Servicers under the Servicing  Agreements with respect to the Mortgage Loans and
(d) proceeds of all the foregoing.

     In connection with such assignment,  the Seller shall, with respect to each
Mortgage Loan, deliver, or cause to be delivered, to the Trust Administrator, as
initial  custodian,  on or before the Closing Date, an Owner Mortgage Loan File.
If any Mortgage or an assignment of a Mortgage to the Trust Administrator or any
prior  assignment is in the process of being  recorded on the Closing Date,  the
Seller  shall  deliver a copy  thereof,  certified  by Norwest  Mortgage  or the
applicable Norwest Mortgage  Correspondent to be a true and complete copy of the
document sent for recording,  and the Seller shall use its best efforts to cause
each such original  recorded  document or certified copy thereof to be delivered
to the Trust Administrator  promptly following its recordation,  but in no event
later than one (1) year  following the Closing Date. The Seller shall also cause
to be delivered to the Trust  Administrator  any other  original  mortgage  loan
document to be included in the Owner  Mortgage  Loan File if a copy  thereof has
been  delivered.  The Seller shall pay from its own funds,  without any right of
reimbursement  therefor,  the  amount of any  costs,  liabilities  and  expenses
incurred by the Trust  Estate by reason of the failure of the Seller to cause to
be  delivered  to the Trust  Administrator  within  one (1) year  following  the
Closing Date any original  Mortgage or assignment of a Mortgage not delivered to
the Trust Administrator on the Closing Date.

     In lieu of recording an  assignment  of any Mortgage the Seller may, to the
extent set forth in any Servicing Agreement, deliver or cause to be delivered to
the Trust  Administrator  the assignment of the Mortgage Loan from the Seller to
the Trust  Administrator  in a form suitable for  recordation,  together with an
Opinion of Counsel to the effect that  recording  is not required to protect the
Trustee's  right,  title and interest in and to the related Mortgage Loan or, in
case a  court  should  recharacterize  the  sale  of  the  Mortgage  Loans  as a
financing, to perfect a first priority security interest in favor of the Trustee
in the related  Mortgage  Loan. In the event that the Master  Servicer  receives
notice that  recording  is required to protect the right,  title and interest of
the  Trustee  in and to any such  Mortgage  Loan  for  which  recordation  of an
assignment has not previously been required,  the Master Servicer shall promptly
notify the Trust  Administrator  and the Trust  Administrator  shall within five
Business Days (or such other  reasonable  period of time mutually agreed upon by
the Master Servicer and the Trust  Administrator)  of its receipt of such notice
deliver  each  previously  unrecorded  assignment  to the related  Servicer  for
recordation.

Section 2.02.     Acceptance by Trust Administrator.

     The Trust Administrator on behalf of the Trustee,  acknowledges  receipt of
the Mortgage Notes, the Mortgages,  the assignments and other documents required
to be delivered on the Closing Date  pursuant to Section 2.01 above and declares
that it holds and will hold such documents and the other documents  constituting
a part of the Owner  Mortgage  Loan  Files  delivered  to it in trust,  upon the
trusts  herein set forth,  for the use and  benefit  of all  present  and future
Certificateholders.   The  Trust  Administrator   agrees,  for  the  benefit  of
Certificateholders, to review each Owner Mortgage Loan File within 45 days after
execution of this  Agreement in order to ascertain  that all required  documents
set forth in Section 2.01 have been executed and received and appear  regular on
their face, and that such documents  relate to the Mortgage Loans  identified in
the Mortgage Loan Schedule,  and in so doing the Trust Administrator may rely on
the  purported due  execution  and  genuineness  of any such document and on the
purported genuineness of any signature thereon. If within such 45 day period the
Trust Administrator finds any document  constituting a part of an Owner Mortgage
Loan  File not to have been  executed  or  received  or to be  unrelated  to the
Mortgage Loans identified in the Mortgage Loan Schedule or not to appear regular
on its face, the Trust  Administrator  shall promptly (and in no event more than
30 days after the discovery of such defect) notify the Seller,  which shall have
a period of 60 days  after the date of such  notice  within  which to correct or
cure any such  defect.  The Seller  hereby  covenants  and agrees  that,  if any
material defect is not so corrected or cured, the Seller will, not later than 60
days after the Trust  Administrator's  notice to it referred to above respecting
such defect,  either (i)  repurchase  the related  Mortgage Loan or any property
acquired in respect  thereof  from the Trust Estate at a price equal to (a) 100%
of the unpaid principal  balance of such Mortgage Loan plus (b) accrued interest
at the  Mortgage  Interest  Rate through the last day of the month in which such
repurchase  takes place or (ii) if within two years of the Startup  Day, or such
other period permitted by the REMIC Provisions, substitute for any Mortgage Loan
to which such  material  defect  relates,  a new  mortgage  loan (a  "Substitute
Mortgage  Loan") having such  characteristics  so that the  representations  and
warranties of the Seller set forth in Section 2.03(b) hereof (other than Section
2.03(b)(i))  would not have been  incorrect  had such  Substitute  Mortgage Loan
originally been a Mortgage Loan. In no event shall any Substitute  Mortgage Loan
have an unpaid principal balance,  as of the date of substitution,  greater than
the Scheduled  Principal  Balance (reduced by the scheduled payment of principal
due on the Due Date in the month of substitution) of the Mortgage Loan for which
it is  substituted.  In addition,  such  Substitute  Mortgage  Loan shall have a
Loan-to-Value  Ratio less than or equal to and a Mortgage Interest Rate equal to
that of the Mortgage Loan for which it is substituted.

     In the case of a repurchased Mortgage Loan or property,  the purchase price
shall be deposited by the Seller in the  Certificate  Account  maintained by the
Master Servicer  pursuant to Section 3.01. In the case of a Substitute  Mortgage
Loan,  the Owner  Mortgage Loan File relating  thereto shall be delivered to the
Trust  Administrator and the Substitution  Principal  Amount,  together with (i)
interest on such  Substitution  Principal  Amount at the applicable Net Mortgage
Interest  Rate to the  following  Due Date of such  Mortgage Loan which is being
substituted for and (ii) an amount equal to the aggregate amount of unreimbursed
Periodic Advances in respect of interest  previously made by a Servicer,  Master
Servicer or Trust  Administrator  with respect to such Mortgage  Loan,  shall be
deposited in the  Certificate  Account.  The Monthly  Payment on the  Substitute
Mortgage Loan for the Due Date in the month of substitution shall not be part of
the  Trust  Estate.   Upon  receipt  by  the  Trust   Administrator  of  written
notification of any such deposit signed by an officer of the Seller,  or the new
Owner  Mortgage  Loan File,  as the case may be, the Trust  Administrator  shall
release to the Seller the related Owner Mortgage Loan File and shall execute and
deliver  such  instrument  of  transfer  or  assignment,  in each  case  without
recourse,  as shall be  necessary  to vest in the  Seller  legal and  beneficial
ownership of such  substituted or repurchased  Mortgage Loan or property.  It is
understood  and agreed that the  obligation  of the Seller to  substitute  a new
Mortgage Loan for or repurchase any Mortgage Loan or property as to which such a
material  defect in a  constituent  document  exists shall  constitute  the sole
remedy  respecting such defect  available to the  Certificateholders,  the Trust
Administrator  on  behalf  of the  Trustee  and the  Trustee  on  behalf  of the
Certificateholders.  The failure of the Trust  Administrator  to give any notice
contemplated  herein  within  forty-five  (45) days after the  execution of this
Agreement shall not affect or relieve the Seller's  obligation to repurchase any
Mortgage Loan pursuant to this Section 2.02.

     The Trust  Administrator may,  concurrently with the execution and delivery
hereof or at any time thereafter, enter into a Custodial Agreement substantially
in the form of  Exhibit  E hereto  pursuant  to which  the  Trust  Administrator
appoints a Custodian to hold the Mortgage Notes, the Mortgages,  the assignments
and  other  documents  related  to the  Mortgage  Loans  received  by the  Trust
Administrator,  as agent for the Trustee in trust for the benefit of all present
and future  Certificateholders,  which may provide, among other things, that the
Custodian  shall conduct the review of such  documents  required under the first
paragraph of this Section 2.02.

Section 2.03.     Representations and Warranties of the Master
Servicer and the Seller.

     (a) The Master Servicer  hereby  represents and warrants to the Trustee and
the Trust  Administrator for the benefit of  Certificateholders  that, as of the
date of execution of this Agreement:

               (i) The Master Servicer is a national  banking  association  duly
          chartered and validly  existing in good standing under the laws of the
          United States;

               (ii) The execution  and delivery of this  Agreement by the Master
          Servicer and its  performance  and  compliance  with the terms of this
          Agreement will not violate the Master Servicer's  corporate charter or
          by-laws or  constitute  a default (or an event  which,  with notice or
          lapse of time, or both,  would  constitute a default) under, or result
          in the breach of, any material contract, agreement or other instrument
          to which the Master  Servicer is a party or which may be applicable to
          the Servicer or any of its assets;

               (iii) This Agreement,  assuming due authorization,  execution and
          delivery  by the  Trustee,  the Trust  Administrator  and the  Seller,
          constitutes  a valid,  legal  and  binding  obligation  of the  Master
          Servicer,  enforceable  against it in accordance with the terms hereof
          subject  to   applicable   bankruptcy,   insolvency,   reorganization,
          moratorium  and other laws  affecting  the  enforcement  of creditors'
          rights  generally and to general  principles of equity,  regardless of
          whether such enforcement is considered in a proceeding in equity or at
          law;

               (iv) The Master  Servicer is not in default  with  respect to any
          order or decree of any court or any order, regulation or demand of any
          federal,  state, municipal or governmental agency, which default might
          have  consequences  that would  materially  and  adversely  affect the
          condition (financial or other) or operations of the Master Servicer or
          its  properties  or might  have  consequences  that  would  affect its
          performance hereunder; and

               (v) No  litigation  is  pending  or,  to the  best of the  Master
          Servicer's  knowledge,  threatened  against the Master  Servicer which
          would  prohibit its entering  into this  Agreement or  performing  its
          obligations under this Agreement.

     It is understood  and agreed that the  representations  and  warranties set
forth in this Section  2.03(a) shall survive  delivery of the  respective  Owner
Mortgage Loan Files to the Trust Administrator or the Custodian.

     (b) The Seller hereby  represents and warrants to the Trustee and the Trust
Administrator  for the  benefit of  Certificateholders  that,  as of the date of
execution  of this  Agreement,  with  respect  to the  Mortgage  Loans,  or each
Mortgage Loan, as the case may be:

               (i) The  information  set forth in the Mortgage Loan Schedule was
          true  and  correct  in all  material  respects  at the  date or  dates
          respecting  which such  information  is  furnished as specified in the
          Mortgage Loan Schedule;

               (ii)   Immediately   prior  to  the   transfer   and   assignment
          contemplated  herein,  the Seller was the sole owner and holder of the
          Mortgage Loan free and clear of any and all liens, pledges, charges or
          security  interests of any nature and has full right and  authority to
          sell and assign the same;

               (iii) The Mortgage is a valid,  subsisting and enforceable  first
          lien on the property therein described,  and the Mortgaged Property is
          free and clear of all  encumbrances and liens having priority over the
          first lien of the Mortgage  except for liens for real estate taxes and
          special  assessments  not yet due and payable  and liens or  interests
          arising  under  or as a result  of any  federal,  state or local  law,
          regulation  or  ordinance  relating to  hazardous  wastes or hazardous
          substances,  and, if the related  Mortgaged  Property is a condominium
          unit, any lien for common  charges  permitted by statute or homeowners
          association fees; and if the Mortgaged  Property consists of shares of
          a  cooperative  housing  corporation,  any lien for amounts due to the

          any lien of any assignment of rents or maintenance expenses secured by
          the real property owned by the cooperative  housing  corporation;  and
          any  security  agreement,  chattel  mortgage  or  equivalent  document
          related  to,  and  delivered  to  the  Trust  Administrator  or to the
          Custodian  with,  any Mortgage  establishes  in the Seller a valid and
          subsisting first lien on the property described therein and the Seller
          has full right to sell and assign the same to the Trustee;

               (iv)  Neither the Seller nor any prior  holder of the Mortgage or
          the related  Mortgage  Note has  modified  the Mortgage or the related

          subordinated the Mortgage in whole or in part,  released the Mortgaged
          Property  in  whole  or in part  from  the  lien of the  Mortgage,  or
          executed any  instrument  of release,  cancellation,  modification  or
          satisfaction,  except in each  case as is  reflected  in an  agreement
          delivered  to the Trust  Administrator  or the  Custodian  pursuant to
          Section 2.01;

               (v) All taxes, governmental assessments,  insurance premiums, and

          owing have been paid, or an escrow of funds has been  established,  to
          the extent permitted by law, in an amount  sufficient to pay for every
          such item which remains unpaid; and the Seller has not advanced funds,
          or received any advance of funds by a party other than the  Mortgagor,
          directly  or   indirectly   (except   pursuant  to  any  Subsidy  Loan
          arrangement)  for the payment of any amount  required by the Mortgage,
          except for interest  accruing  from the date of the  Mortgage  Note or
          date of  disbursement  of the  Mortgage  Loan  proceeds,  whichever is
          later,  to the day which  precedes  by thirty  days the first Due Date
          under the related Mortgage Note;

               (vi)  The  Mortgaged   Property  is  undamaged  by  water,  fire,
          earthquake,  earth movement other than earthquake,  windstorm,  flood,
          tornado or similar casualty  (excluding  casualty from the presence of
          hazardous wastes or hazardous substances, as to which the Seller makes
          no  representations),  so as to  affect  adversely  the  value  of the
          Mortgaged  Property as security for the  Mortgage  Loan or the use for
          which  the  premises  were  intended  and to the best of the  Seller's
          knowledge,  there is no proceeding pending or threatened for the total
          or partial condemnation of the Mortgaged Property;

               (vii) The Mortgaged  Property is free and clear of all mechanics'
          and  materialmen's  liens or liens in the  nature  thereof;  provided,
          however,  that this warranty  shall be deemed not to have been made at
          the time of the initial issuance of the Certificates if a title policy
          affording, in substance, the same protection afforded by this warranty
          is furnished to the Trust Administrator by the Seller;

               (viii)  Except for  Mortgage  Loans  secured by Co-op  Shares and
          Mortgage Loans secured by residential  long-term leases, the Mortgaged
          Property consists of a fee simple estate in real property;  all of the
          improvements  which are  included for the purpose of  determining  the

          the  legal,  valid  and  binding  obligation  of  the  maker  thereof,
          enforceable in accordance with its terms,  except as such  enforcement
          may be  limited by  bankruptcy,  insolvency,  reorganization  or other
          similar laws affecting the enforcement of creditors'  rights generally
          and  by  general  equity   principles   (regardless  of  whether  such

               (xv) The Mortgage  Loan (except any Mortgage  Loan  identified on
          the Mortgage Loan Schedule as a T.O.P.  Mortgage Loan and any Mortgage
          Loan secured by  Mortgaged  Property  located in Iowa,  as to which an
          opinion of counsel of the type  customarily  rendered in such State in
          lieu of title insurance is instead received) is covered by an American
          Land  Title  Association  mortgagee  title  insurance  policy or other
          generally acceptable form of policy or insurance acceptable to FNMA or
          FHLMC,  issued by a title insurer acceptable to FNMA or FHLMC insuring
          the originator,  its successors and assigns,  as to the first priority
          lien of the Mortgage in the original  principal amount of the Mortgage
          Loan and subject only to (A) the lien of current real  property  taxes
          and assessments not yet due and payable, (B) covenants, conditions and
          restrictions,  rights of way,  easements  and other  matters of public
          record as of the date of  recording  of such  Mortgage  acceptable  to
          mortgage  lending  institutions  in the  area in which  the  Mortgaged
          Property  is  located or  specifically  referred  to in the  appraisal
          performed in connection with the  origination of the related  Mortgage
          Loan, (C) liens created  pursuant to any federal,  state or local law,
          regulation or ordinance  affording  liens for the costs of clean-up of
          hazardous  substances or hazardous  wastes or for other  environmental
          protection   purposes  and  (D)  such  other  matters  to  which  like
          properties are commonly subject which do not  individually,  or in the
          aggregate,  materially  interfere  with the  benefits of the  security
          intended  to be  provided  by the  Mortgage;  the  Seller  is the sole
          insured of such mortgagee  title insurance  policy,  the assignment to
          the Trust  Administrator,  on behalf of the  Trustee,  of the Seller's
          interest in such mortgagee title insurance policy does not require any
          consent of or  notification to the insurer which has not been obtained
          or made, such mortgagee  title  insurance  policy is in full force and
          effect and will be in full  force and effect and inure to the  benefit
          of the Trust  Administrator  on behalf of the Trustee,  no claims have
          been made under such mortgagee  title insurance  policy,  and no prior
          holder of the related Mortgage, including the Seller, has done, by act
          or  omission,  anything  which  would  impair  the  coverage  of  such
          mortgagee title insurance policy;

               (xvi) The  Mortgaged  Property  securing  each  Mortgage  Loan is
          insured by an insurer acceptable to FNMA or FHLMC against loss by fire
          and such  hazards as are covered  under a standard  extended  coverage
          endorsement, in an amount which is not less than the lesser of 100% of
          the  insurable  value of the  Mortgaged  Property and the  outstanding
          principal  balance of the Mortgage Loan, but in no event less than the
          minimum amount necessary to fully compensate for any damage or loss on
          a replacement  cost basis; if the Mortgaged  Property is a condominium
          unit, it is included  under the coverage  afforded by a blanket policy
          for the  project;  if  upon  origination  of the  Mortgage  Loan,  the
          improvements  on the Mortgaged  Property were in an area identified in
          the Federal  Register by the Federal  Emergency  Management  Agency as
          having special flood  hazards,  a flood  insurance  policy meeting the
          requirements  of  the  current  guidelines  of the  Federal  Insurance
          Administration  is in effect  with a  generally  acceptable  insurance
          carrier, in an amount representing coverage not less than the least of
          (A) the  outstanding  principal  balance of the Mortgage Loan, (B) the
          full  insurable  value of the  Mortgaged  Property and (C) the maximum
          amount of  insurance  which  was  available  under the Flood  Disaster
          Protection  Act of 1973;  and each  Mortgage  obligates  the Mortgagor
          thereunder to maintain all such insurance at the Mortgagor's  cost and
          expense;

               (xvii)  To  the  best  of the  Seller's  knowledge,  there  is no
          default, breach, violation or event of acceleration existing under the
          Mortgage or the related  Mortgage  Note and no event  which,  with the
          passage of time or with notice and the expiration of any grace or cure
          period,  would  constitute  a default,  breach,  violation or event of
          acceleration; the Seller has not waived any default, breach, violation
          or event of  acceleration;  and no  foreclosure  action  is  currently
          threatened or has been commenced with respect to the Mortgage Loan;

               (xviii) No  Mortgage  Note or Mortgage is subject to any right of
          rescission, set-off, counterclaim or defense, including the defense of
          usury, nor will the operation of any of the terms of the Mortgage Note
          or  Mortgage,  or the  exercise  of any right  thereunder,  render the
          Mortgage  Note or  Mortgage  unenforceable,  in whole  or in part,  or
          subject  it to any  right  of  rescission,  set-off,  counterclaim  or
          defense,  including  the  defense  of  usury,  and no  such  right  of
          rescission,  set-off,  counterclaim  or defense has been asserted with
          respect thereto;

               (xix)  Each  Mortgage  Note  is  payable  in  monthly   payments,
          resulting in complete amortization of the Mortgage Loan over a term of
          not more than 360 months;

               (xx) Each Mortgage contains customary and enforceable  provisions
          such as to render  the  rights  and  remedies  of the  holder  thereof
          adequate for the  realization  against the  Mortgaged  Property of the
          benefits  of  the   security,   including   realization   by  judicial
          foreclosure  (subject to any limitation  arising from any  bankruptcy,
          insolvency  or other law for the relief of  debtors),  and there is no
          homestead or other  exemption  available to the Mortgagor  which would
          interfere with such right of foreclosure;

               (xxi) To the best of the  Seller's  knowledge,  no Mortgagor is a
          debtor in any state or federal bankruptcy or insolvency proceeding;

               (xxii) Each  Mortgaged  Property is located in the United  States
          and consists of a one- to four-unit  residential  property,  which may
          include a detached home,  townhouse,  condominium  unit or a unit in a
          planned unit  development or, in the case of Mortgage Loans secured by
          Co-op Shares, leases or occupancy agreements;

               (xxiii) The Mortgage  Loan is a "qualified  mortgage"  within the
          meaning of Section 860G of the Code;

               (xxiv) With respect to each Mortgage  where a lost note affidavit
          has been delivered to the Trust  Administrator in place of the related
          Mortgage Note, the related Mortgage Note is no longer in existence;

               (xxv) In the event that the Mortgagor is an inter vivos  "living"
          trust,  (i) such trust is in compliance  with FNMA or FHLMC  standards
          for  inter  vivos  trusts  and (ii)  holding  title  to the  Mortgaged
          Property  in such  trust  will not  diminish  any rights as a creditor
          including  the right to full title to the  Mortgaged  Property  in the
          event foreclosure proceedings are initiated; and

               (xxvi) If the Mortgage Loan is secured by a long-term residential
          lease,  (1) the lessor under the lease holds a fee simple  interest in
          the land; (2) the terms of such lease expressly  permit the mortgaging
          of the  leasehold  estate,  the  assignment  of the lease  without the
          lessor's  consent and the acquisition by the holder of the Mortgage of
          the rights of the lessee upon  foreclosure  or  assignment  in lieu of
          foreclosure  or provide the holder of the Mortgage with  substantially
          similar protections;  (3) the terms of such lease do not (a) allow the
          termination  thereof upon the lessee's  default  without the holder of
          the  Mortgage  being  entitled  to  receive  written  notice  of,  and
          opportunity to cure,  such default,  (b) allow the  termination of the
          lease in the event of damage or destruction as long as the Mortgage is
          in  existence,  (c)  prohibit  the holder of the  Mortgage  from being
          insured  (or  receiving   proceeds  of  insurance)  under  the  hazard
          insurance policy or policies relating to the Mortgaged Property or (d)
          permit any increase in rent other than  pre-established  increases set
          forth in the lease;  (4) the  original  term of such lease is not less
          than 15 years;  (5) the term of such lease does not terminate  earlier
          than five years after the maturity date of the Mortgage  Note; and (6)
          the Mortgaged  Property is located in a jurisdiction  in which the use
          of  leasehold   estates  in  transferring   ownership  in  residential
          properties is a widely accepted practice.

     Notwithstanding the foregoing, no representations or warranties are made by
the Seller as to the  environmental  condition of any  Mortgaged  Property;  the
absence,  presence or effect of hazardous wastes or hazardous  substances on any
Mortgaged  Property;  any  casualty  resulting  from the  presence  or effect of
hazardous  wastes  or  hazardous  substances  on,  near or  emanating  from  any
Mortgaged  Property;  the  impact  on  Certificateholders  of any  environmental
condition  or  presence  of any  hazardous  substance  on or near any  Mortgaged
Property;  or the  compliance of any Mortgaged  Property with any  environmental
laws, nor is any agent,  person or entity  otherwise  affiliated with the Seller
authorized  or able to make any such  representation,  warranty or assumption of
liability relative to any Mortgaged Property. In addition, no representations or
warranties are made by the Seller with respect to the absence or effect of fraud
in the origination of any Mortgage Loan.

     It is understood  and agreed that the  representations  and  warranties set
forth in this Section  2.03(b) shall survive  delivery of the  respective  Owner
Mortgage Loan Files to the Trust Administrator and shall inure to the benefit of
the  Trust  Administrator,   on  behalf  of  the  Trustee   notwithstanding  any
restrictive or qualified endorsement or assignment.

     (c) Upon discovery by either the Seller, the Master Servicer,  the Trustee,
the Trust  Administrator  or the Custodian that any of the  representations  and
warranties made in subsection (b) above is not accurate (referred to herein as a
"breach") and that such breach materially and adversely affects the interests of
the  Certificateholders in the related Mortgage Loan, the party discovering such
breach shall give prompt  written  notice to the other  parties  (any  Custodian
being so obligated under a Custodial  Agreement).  Within 60 days of the earlier
of its  discovery or its receipt of notice of any such breach,  the Seller shall
cure such breach in all  material  respects or shall either (i)  repurchase  the
Mortgage Loan or any property  acquired in respect thereof from the Trust Estate
at a price equal to (A) 100% of the unpaid  principal  balance of such  Mortgage
Loan  plus (B)  accrued  interest  at the Net  Mortgage  Interest  Rate for such
Mortgage  Loan through the last day of the month in which such  repurchase  took
place or (ii) if within  two years of the  Startup  Day,  or such  other  period
permitted by the REMIC  Provisions,  substitute  for such  Mortgage  Loan in the
manner described in Section 2.02. The purchase price of any repurchase described
in this paragraph and the Substitution  Principal  Amount,  if any, plus accrued
interest  thereon and the other amounts  referred to in Section  2.02,  shall be
deposited  in the  Certificate  Account.  It is  understood  and agreed that the
obligation of the Seller to  repurchase  or substitute  for any Mortgage Loan or
property  as to  which  such a  breach  has  occurred  and is  continuing  shall
constitute   the   sole   remedy    respecting   such   breach    available   to
Certificateholders,  the Trust  Administrator  on behalf of the  Trustee  or the
Trustee on behalf of Certificateholders, and such obligation shall survive until
termination of the Trust Estate hereunder.

Section 2.04.     Execution and Delivery of Certificates.

     The Trust  Administrator  acknowledges the assignment to it of the Mortgage
Loans and the delivery of the Owner Mortgage Loan Files to it, and, concurrently
with such delivery, (i) acknowledges the issuance of and hereby declares that it
holds the Uncertificated  Lower-Tier Interests on behalf of the Upper-Tier REMIC
and  Certificateholders and (ii) has executed and delivered to or upon the order
of the Seller, in exchange for the Mortgage Loans and Uncertificated  Lower-Tier
Interests  together with all other assets  included in the  definition of "Trust
Estate",  receipt of which is hereby  acknowledged,  Certificates  in authorized
denominations  which,  together with the  Uncertificated  Lower-Tier  Interests,
evidence ownership of the entire Trust Estate.

Section 2.05.  Designation of Certificates; Designation of Startup Day and
               Latest Possible Maturity Date.

     The Seller hereby designates the Subclasses of Class A Certificates  (other
than the Class A-R and Class A-LR Certificates),  the Class M Certificates,  the
Subclasses of Class B  Certificates  as classes of "regular  interests"  and the
Class  A-R  Certificate  as the  single  class  of  "residual  interest"  in the
Upper-Tier  REMIC for the purposes of Code Sections  860G(a)(1) and  860G(a)(2),
respectively.  The Seller hereby  further  designates  the Class A-L1  Interest,
Class A-L2 Interest,  Class A-L9 Interest,  Class A-LPO,  Class A-LIO  Interest,
Class A-LPO  Interest,  Class A-LUR  Interest,  Class B-L1 Interest,  Class B-L2
Interest,  Class B-L3  Interest,  Class B-L4  Interest,  Class B-L5 Interest and
Class M-L  Interest  as  classes  of  "regular  interests"  and the  Class  A-LR
Certificate as the single class of "residual  interest" in the Lower-Tier  REMIC
for the purposes of Code Sections 860G(a)(1) and 860G(a)(2),  respectively.  The
Closing Date is hereby designated as the "Startup Day" of each of the Upper-Tier
REMIC and Lower-Tier  REMIC within the meaning of Code Section  860G(a)(9).  The
"latest possible maturity date" of the regular interests in the Upper-Tier REMIC
and  Lower-Tier  REMIC  is  December  25,  2027  for  purposes  of Code  Section

ARTICLE III

ADMINISTRATION OF THE TRUST ESTATE:  SERVICING
OF THE MORTGAGE LOANS

Section 3.01.     Certificate Account.

     (a) The Master Servicer shall establish and maintain a Certificate  Account
for the deposit of funds  received by the Master  Servicer  with  respect to the
Mortgage  Loans  serviced by each  Servicer  pursuant  to each of the  Servicing
Agreements.  Such account shall be maintained as an Eligible Account. The Master
Servicer  shall give notice to each  Servicer  and the Seller of the location of
the Certificate Account and of any change in the location thereof.

     (b) The Master Servicer shall deposit into the  Certificate  Account on the
day of receipt thereof all amounts received by it from any Servicer  pursuant to
any of the  Servicing  Agreements,  and shall,  in  addition,  deposit  into the
Certificate  Account the following amounts,  in the case of amounts specified in
clause  (i),  not later than the  Distribution  Date on which such  amounts  are
required to be distributed to Certificateholders and, in the case of the amounts
specified in clause (ii), not later than the Business Day next following the day
of receipt and posting by the Master Servicer:

          (i) Periodic  Advances  pursuant to Section 3.03(a) made by the Master
     Servicer or the Trust Administrator, if any and any amounts deemed received
     by the Master Servicer pursuant to Section 3.01(d); and

          (ii) in the  case of any  Mortgage  Loan  that is  repurchased  by the
     Seller  pursuant to Section 2.02 or 2.03 or that is auctioned by the Master
     Servicer  pursuant  to Section  3.08 or  purchased  by the Master  Servicer
     pursuant to Section  3.08 or 9.01,  the purchase  price  therefor or, where
     applicable,  any Substitution  Principal Amount and any amounts received in
     respect of the interest portion of unreimbursed Periodic Advances.

     (c) The Master Servicer shall cause the funds in the Certificate Account to
be invested in Eligible  Investments.  No such Eligible Investments will be sold
or  disposed  of at a gain prior to  maturity  unless the  Master  Servicer  has
received an Opinion of Counsel or other  evidence  satisfactory  to it that such
sale or disposition  will not cause the Trust Estate to be subject to Prohibited
Transactions Tax,  otherwise subject the Trust Estate to tax, or cause either of
the Upper-Tier REMIC or the Lower-Tier REMIC to fail to qualify as a REMIC while
any  Certificates  are  outstanding.  Any amounts  deposited in the  Certificate
Account prior to the Distribution  Date shall be invested for the account of the
Master   Servicer  and  any  investment   income  thereon  shall  be  additional
compensation to the Master Servicer for services  rendered under this Agreement.
The amount of any losses  incurred in respect of any such  investments  shall be
deposited in the Certificate Account by the Master Servicer out of its own funds
immediately as realized.

     (d) For purposes of this  Agreement,  the Master Servicer will be deemed to
have received from a Servicer on the applicable  Remittance  Date for such funds
all  amounts  deposited  by such  Servicer  into the  Custodial  Account for P&I
maintained  in  accordance  with the  applicable  Servicing  Agreement,  if such
Custodial  Account  for  P&I is not an  Eligible  Account  as  defined  in  this
Agreement,  to the extent such amounts are not  actually  received by the Master
Servicer  on such  Remittance  Date as a result of the  bankruptcy,  insolvency,
receivership or other financial distress of the depository  institution in which
such  Custodial  Account  for P&I is being held.  To the extent that  amounts so
deemed to have been received by the Master Servicer are subsequently remitted to
the Master  Servicer,  the Master  Servicer  shall be  entitled  to retain  such
amounts.

Section 3.02.     Permitted Withdrawals from the Certificate Account.

     (a) The Master Servicer may, from time to time, make  withdrawals  from the
Certificate Account for the following purposes (limited, in the case of Servicer
reimbursements, to cases where funds in the respective Custodial P&I Account are
not sufficient therefor):

          (i) to reimburse the Master Servicer,  the Trust  Administrator or any
     Servicer for  Periodic  Advances  made by the Master  Servicer or the Trust
     Administrator  pursuant to Section 3.03(a) or any Servicer  pursuant to any
     Servicing Agreement with respect to previous Distribution Dates, such right
     to  reimbursement  pursuant to this  subclause (i) being limited to amounts
     received on or in respect of particular Mortgage Loans (including, for this
     purpose, Liquidation Proceeds, REO Proceeds and proceeds from the purchase,
     sale,  repurchase or  substitution  of Mortgage  Loans pursuant to Sections
     2.02,  2.03, 3.08 or 9.01)  respecting  which any such Periodic Advance was
     made;

          (ii) to  reimburse  any  Servicer,  the Master  Servicer  or the Trust
     Administrator  for any Periodic  Advances  determined in good faith to have
     become Nonrecoverable Advances;

          (iii)  to  reimburse   the  Master   Servicer  or  any  Servicer  from
     Liquidation  Proceeds for Liquidation  Expenses and for amounts expended by
     the Master  Servicer or any Servicer  pursuant  hereto or to any  Servicing
     Agreement,  respectively,  in good faith in connection with the restoration
     of damaged property or for foreclosure expenses;

          (iv) from any  Mortgagor  payment  on  account  of  interest  or other
     recovery (including Net REO Proceeds) with respect to a particular Mortgage
     Loan, to pay the Master Servicing Fee with respect to such Mortgage Loan to
     the Master Servicer;

          (v) to  reimburse  the  Master  Servicer,  any  Servicer  or the Trust
     Administrator  (or, in certain cases, the Seller) for expenses  incurred by
     it (including  taxes paid on behalf of the Trust Estate) and recoverable by
     or reimbursable to it pursuant to Section  3.03(c),  3.03(d) or 6.03 or the
     second sentence of Section 8.14(a) or pursuant to such Servicer's Servicing
     Agreement, provided such expenses are "unanticipated" within the meaning of
     the REMIC Provisions;

          (vi) to pay to the  Seller or other  purchaser  with  respect  to each
     Mortgage  Loan or  property  acquired  in  respect  thereof  that  has been
     repurchased  or  replaced  pursuant  to Section  2.02 or 2.03 or  auctioned
     pursuant to Section 3.08 or to pay to the Master  Servicer  with respect to
     each  Mortgage Loan or property  acquired in respect  thereof that has been
     purchased  pursuant to Section 3.08 or 9.01, all amounts  received  thereon
     and not  required  to be  distributed  as of the date on which the  related
     repurchase or purchase price or Scheduled Principal Balance was determined;

          (vii) to remit  funds to the Paying  Agent in the  amounts  and in the
     manner provided for herein;

          (viii)  to  pay to the  Master  Servicer  any  interest  earned  on or
     investment income with respect to funds in the Certificate Account;

          (ix)  to  pay to  the  Master  Servicer  or  any  Servicer  out of Net
     Liquidation  Proceeds allocable to interest the amount of any unpaid Master
     Servicing  Fee or Servicing  Fee (as adjusted  pursuant to such  Servicer's
     Servicing  Agreement) and any unpaid  assumption fees, late payment charges
     or other Mortgagor charges on the related Mortgage Loan;

          (x) to withdraw from the Certificate  Account any amount  deposited in
     the Certificate Account that was not required to be deposited therein; and

          (xi) to clear  and  terminate  the  Certificate  Account  pursuant  to
     Section 9.01.

     (b) The Master Servicer shall keep and maintain separate  accounting,  on a
Mortgage Loan by Mortgage Loan basis,  for the purpose of justifying any payment
to and withdrawal from the Certificate Account.

Section 3.03.     Advances by Master Servicer and Trust Administrator.

     (a) In the  event an Other  Servicer  fails to make any  required  Periodic
Advances of principal and interest on a Mortgage Loan as required by the related
Other Servicing  Agreement prior to the Distribution Date occurring in the month
during  which such  Periodic  Advance is due,  the  Master  Servicer  shall make
Periodic  Advances to the extent provided hereby.  In the event Norwest Mortgage
fails to make any  required  Periodic  Advances of  principal  and interest on a
Mortgage  Loan as  required  by the  Norwest  Servicing  Agreement  prior to the
Distribution  Date occurring in the month during which such Periodic  Advance is
due, the Trust Administrator shall, to the extent required by Section 8.15, make
such Periodic  Advance to the extent  provided  hereby,  provided that the Trust
Administrator  has previously  received the  certificate of the Master  Servicer
described in the following  sentence.  The Master  Servicer shall certify to the
Trust Administrator with respect to any such Distribution Date (i) the amount of
Periodic  Advances  required of Norwest Mortgage or such Other Servicer,  as the
case may be, (ii) the amount actually advanced,  (iii) the amount that the Trust
Administrator  or Master  Servicer  is required  to advance  hereunder  and (iv)
whether the Master Servicer has determined that it reasonably believes that such
Periodic  Advance is a  Nonrecoverable  Advance.  Amounts  advanced by the Trust
Administrator  or Master Servicer shall be deposited in the Certificate  Account
on the related  Distribution Date.  Notwithstanding  the foregoing,  neither the
Master Servicer nor the Trust Administrator will be obligated to make a Periodic
Advance that it reasonably  believes to be a Nonrecoverable  Advance.  The Trust
Administrator  may  conclusively  rely  for any  determination  to be made by it
hereunder  upon the  determination  of the Master  Servicer  as set forth in its
certificate.

     (b) To the extent an Other  Servicer fails to make an advance on account of
the taxes or  insurance  premiums  with  respect  to a  Mortgage  Loan  required
pursuant to the related Other Servicing Agreement, the Master Servicer shall, if
the Master  Servicer  knows of such failure of the Servicer,  advance such funds
and take such steps as are necessary to pay such taxes or insurance premiums. To
the extent Norwest  Mortgage fails to make an advance on account of the taxes or
insurance  premiums  with respect to a Mortgage  Loan  required  pursuant to the
Norwest Servicing  Agreement,  the Master Servicer shall, if the Master Servicer
knows of such failure of Norwest  Mortgage,  certify to the Trust  Administrator
that such failure has occurred.  Upon receipt of such  certification,  the Trust
Administrator  shall  advance such funds and take such steps as are necessary to
pay such taxes or insurance premiums.

     (c) The Master Servicer and the Trust  Administrator shall each be entitled
to be reimbursed from the Certificate  Account for any Periodic  Advance made by
it under  Section  3.03(a) to the extent  described  in Section  3.02(a)(i)  and
(a)(ii). The Master Servicer and the Trust Administrator shall be entitled to be
reimbursed  pursuant  to Section  3.02(a)(v)  for any  advance by it pursuant to
Section 3.03(b). The Master Servicer shall diligently pursue restoration of such
amount to the Certificate Account from the related Servicer. The Master Servicer
shall,  to the extent it has not already  done so, upon the request of the Trust
Administrator,  withdraw  from the  Certificate  Account  and remit to the Trust
Administrator  any  amounts  to which the Trust  Administrator  is  entitled  as
reimbursement pursuant to Section 3.02 (a)(i), (ii) and (v).

     (d) Except as  provided  in Section  3.03(a)  and (b),  neither  the Master
Servicer  nor the Trust  Administrator  shall be  required to pay or advance any
amount  which  any  Servicer  was  required,  but  failed,  to  deposit  in  the
Certificate Account.

Section 3.04.     Trust Administrator to Cooperate;
Release of Owner Mortgage Loan Files.

     Upon the  receipt  by the  Master  Servicer  of a Request  for  Release  in
connection  with the deposit by a Servicer into the  Certificate  Account of the
proceeds from a Liquidated  Loan or of a Prepayment in Full, the Master Servicer
shall  confirm  to the  Trust  Administrator  that all  amounts  required  to be
remitted to the  Certificate  Account in connection with such Mortgage Loan have
been so  deposited,  and shall  deliver  such  Request  for Release to the Trust
Administrator.  The Trust Administrator  shall, within five Business Days of its
receipt of such a Request for Release,  release the related Owner  Mortgage Loan
File to the  Master  Servicer  or such  Servicer,  as  requested  by the  Master
Servicer. No expenses incurred in connection with any instrument of satisfaction
or deed of reconveyance shall be chargeable to the Certificate Account.

     From time to time and as  appropriate  for the servicing or  foreclosure of
any Mortgage Loan,  including but not limited to, collection under any insurance
policies, or to effect a partial release of any Mortgaged Property from the lien
of the Mortgage,  the Servicer of such Mortgage Loan shall deliver to the Master
Servicer a Request for Release.  Upon the Master Servicer's  receipt of any such
Request for Release,  the Master Servicer shall promptly forward such request to
the Trust Administrator and the Trust Administrator  shall, within five Business
Days,  release the related Owner  Mortgage  Loan File to the Master  Servicer or
such Servicer, as requested by the Master Servicer. Any such Request for Release
shall  obligate  the Master  Servicer or such  Servicer,  as the case may be, to
return each and every document previously requested from the Owner Mortgage Loan
File to the Trust  Administrator  by the  twenty-first day following the release
thereof,  unless (i) the Mortgage Loan has been  liquidated and the  Liquidation
Proceeds  relating to the Mortgage Loan have been  deposited in the  Certificate
Account or (ii) the Owner Mortgage Loan File or such document has been delivered
to an attorney,  or to a public trustee or other public  official as required by
law, for purposes of  initiating or pursuing  legal action or other  proceedings
for  the   foreclosure   of  the  Mortgaged   Property   either   judicially  or
non-judicially, and the Master Servicer has delivered to the Trust Administrator
a certificate of the Master Servicer or such Servicer  certifying as to the name
and  address  of the  Person  to which  such  Owner  Mortgage  Loan File or such
document  was  delivered  and the  purpose or purposes  of such  delivery.  Upon
receipt of an  Officer's  Certificate  of the Master  Servicer or such  Servicer
stating that such Mortgage Loan was liquidated and that all amounts  received or
to be received in  connection  with such  liquidation  which are  required to be
deposited  into the  Certificate  Account have been so  deposited,  or that such
Mortgage Loan has become an REO Mortgage  Loan, the Request for Release shall be
released by the Trust Administrator to the Master Servicer or such Servicer,  as
appropriate.

     Upon written  certification  of the Master Servicer or the Servicer of such
Mortgage Loan, the Trust  Administrator  shall execute and deliver to the Master
Servicer or such Servicer, as directed by the Master Servicer,  court pleadings,
requests for trustee's sale or other  documents  necessary to the foreclosure or
trustee's sale in respect of a Mortgaged Property or to any legal action brought
to obtain judgment  against any Mortgagor on the Mortgage Note or Mortgage or to
obtain a  deficiency  judgment,  or to  enforce  any  other  remedies  or rights
provided by the Mortgage  Note or Mortgage or  otherwise  available at law or in
equity.  Each such certification  shall include a request that such pleadings or
documents  be executed  by the Trust  Administrator  and a  statement  as to the
reason such  documents or pleadings  are  required  and that the  execution  and
delivery  thereof by the Trust  Administrator  will not  invalidate or otherwise
affect the lien of the Mortgage,  except for the termination of such a lien upon
completion of the foreclosure proceeding or trustee's sale.

Section 3.05.     Reports to the Trustee and Trust Administrator;
Annual Compliance Statements.

     (a) Not  later  than 15 days  after  each  Distribution  Date,  the  Master
Servicer  shall deliver to the Trustee and the Trust  Administrator  a statement
setting forth the status of the Certificate  Account as of the close of business
on such Distribution Date stating that all distributions  required to be made by
the Master  Servicer  under this  Agreement  have been made (or, if any required
distribution has not been made by the Master Servicer, specifying the nature and
status  thereof)  and showing,  for the period  covered by such  statement,  the
aggregate  amount of deposits  into and  withdrawals  from such account for each
category of deposit and  withdrawal  specified in Sections  3.01 and 3.02.  Such
statement may be in the form of the then current FNMA monthly  accounting report
for its Guaranteed Mortgage  Pass-Through Program with appropriate additions and
changes, and shall also include information as to the aggregate unpaid principal
balance of all of the Mortgage  Loans as of the close of business as of the last
day of the calendar month immediately  preceding such Distribution  Date. Copies
of  such  statement  shall  be  provided  by  the  Trust  Administrator  to  any
Certificateholder upon written request, provided such statement is delivered, or
caused to be delivered, by the Master Servicer to the Trust Administrator.

     (b) The  Master  Servicer  shall  deliver  to the  Trustee  and  the  Trust
Administrator  on or before  April 30 of each year, a  certificate  signed by an
officer of the Master  Servicer,  certifying  that (i) such officer has reviewed
the  activities of the Master  Servicer  during the  preceding  calendar year or
portion thereof and its performance under this agreement and (ii) to the best of
such  officer's  knowledge,  based  on such  review,  the  Master  Servicer  has
performed and fulfilled its duties,  responsibilities and obligations under this
agreement in all material respects throughout such year, or, if there has been a
default in the fulfillment of any such duties,  responsibilities or obligations,
specifying  each such  default  known to such  officer and the nature and status
thereof,  and, (iii) (A) the Master Servicer has received from each Servicer any
financial statements,  officer's certificates,  accountant's statements or other
information  required  to be  provided  to the Master  Servicer  pursuant to the
related  Servicing  Agreement and (B) to the best of such  officer's  knowledge,
based on a review of the  information  provided  to the Master  Servicer by each
Servicer as  described  in (iii)(A)  above,  each  Servicer  has  performed  and
fulfilled  its  duties,  responsibilities  and  obligations  under  the  related
Servicing  Agreement in all material respects throughout such year, or, if there
has been a default in the  fulfillment of any such duties,  responsibilities  or
obligations,  specifying  each such default known to such officer and the nature
and status thereof.  Copies of such officers'  certificate  shall be provided by
the Trust Administrator to any  Certificateholder  upon written request provided
such certificate is delivered, or caused to be delivered, by the Master Servicer
to the Trust Administrator.

Section 3.06.     Title, Management and Disposition of Any REO
Mortgage Loan.

     The  Master   Servicer   shall  ensure  that  each  REO  Mortgage  Loan  is
administered  by the  related  Servicer  at all  times so that it  qualifies  as
"foreclosure  property" under the REMIC Provisions and that it does not earn any
"net income from  foreclosure  property" which is subject to tax under the REMIC
Provisions.  In the  event  that a  Servicer  is unable  to  dispose  of any REO
Mortgage Loan within the period  mandated by each of the  Servicing  Agreements,
the Master Servicer shall monitor such Servicer to verify that such REO Mortgage
Loan is auctioned to the highest  bidder within the period so specified.  In the
event of any such sale of REO Mortgage Loan, the Trust  Administrator  shall, at
the  written  request  of the Master  Servicer  and upon  being  supported  with
appropriate  forms  therefor,  within five  Business  Days of the deposit by the
Master  Servicer of the  proceeds of such sale or auction  into the  Certificate
Account,  release or cause to be released to the entity identified by the Master
Servicer the related Owner  Mortgage  Loan File and Servicer  Mortgage Loan File
and shall execute and deliver such  instruments  of transfer or  assignment,  in
each  case  without  recourse,  as shall  be  necessary  to vest in the  auction
purchaser title to the REO Mortgage Loan and the Trust  Administrator shall have
no  further  responsibility  with  regard to such  Owner  Mortgage  Loan File or
Servicer  Mortgage  Loan  File.  Neither  the Trust  Administrator,  the  Master
Servicer nor any Servicer,  acting on behalf of the Trust Estate,  shall provide
financing from the Trust Estate to any purchaser of an REO Mortgage Loan.

Section 3.07.  Amendments to Servicing Agreements, Modification of Standard
               Provisions.

     (a)  Subject  to the prior  written  consent of the  Trustee  and the Trust
Administrator pursuant to Section 3.07(b), the Master Servicer from time to time
may, to the extent permitted by the applicable  Servicing  Agreement,  make such
modifications and amendments to such Servicing  Agreement as the Master Servicer
deems necessary or appropriate to confirm or carry out more fully the intent and
purpose  of such  Servicing  Agreement  and  the  duties,  responsibilities  and
obligations to be performed by the Servicer  thereunder.  Such modifications may
only be made if they are consistent with the REMIC  Provisions,  as evidenced by
an Opinion of Counsel.  Prior to the issuance of any  modification or amendment,
the Master  Servicer  shall  deliver to the Trustee and the Trust  Administrator
such  Opinion of Counsel  and an  Officer's  Certificate  setting  forth (i) the
provision that is to be modified or amended,  (ii) the modification or amendment
that the Master  Servicer  desires to issue and (iii) the reason or reasons  for
such proposed amendment or modification.

     (b) The Trustee and the Trust  Administrator shall consent to any amendment
or supplement to a Servicing  Agreement proposed by the Master Servicer pursuant
to Section 3.07(a), which consent and amendment shall not require the consent of
any  Certificateholder  if it is (i) for the  purpose of curing  any  mistake or
ambiguity or to further  effect or protect the rights of the  Certificateholders
or (ii) for any other  purpose,  provided such  amendment or supplement for such
other   purpose   cannot    reasonably   be   expected   to   adversely   affect
Certificateholders.  The lack of reasonable  expectation of an adverse effect on
Certificateholders  may be  established  through the delivery to the Trustee and
the Trust  Administrator  of (i) an Opinion  of  Counsel to such  effect or (ii)
written  notification  from each Rating Agency to the effect that such amendment
or  supplement  will not result in reduction of the current  rating  assigned by
that Rating  Agency to the  Certificates.  Notwithstanding  the two  immediately
preceding  sentences,  either the Trustee or the Trust Administrator may, in its
discretion, decline to enter into or consent to any such supplement or amendment
if its own rights, duties or immunities shall be adversely affected.

     (c)(i)  Notwithstanding  anything to the contrary in this Section 3.07, the
Master   Servicer   from  time  to  time  may,   without   the  consent  of  any
Certificateholder,  the  Trustee  or the  Trust  Administrator,  enter  into  an
amendment (A) to an Other Servicing Agreement for the purpose of (i) eliminating
or reducing  Month End Interest and (ii)  providing  for the  remittance of Full
Unscheduled Principal Receipts by the applicable Servicer to the Master Servicer
not later than the 24th day of each month (or if such day is not a Business Day,
on the previous Business Day) or (B) to the Norwest Servicing  Agreement for the
purpose of changing the applicable Remittance Date to the 18th day of each month
(or if such day is not a Business Day, on the previous Business Day).

     (ii)The  Master  Servicer  may  direct  Norwest  Mortgage  to enter into an
amendment  to the Norwest  Servicing  Agreement  for the  purposes  described in
Sections 3.07(c)(i)(B) and 10.01(b)(iii).

Section 3.08.     Oversight of Servicing.

     The Master Servicer shall  supervise,  monitor and oversee the servicing of
the Mortgage Loans by each Servicer and the  performance by each Servicer of all
services,  duties,  responsibilities  and obligations that are to be observed or
performed  by  the  Servicer  under  its  respective  Servicing  Agreement.   In
performing its obligations hereunder,  the Master Servicer shall act in a manner
consistent with Accepted Master Servicing Practices and with the Trustee's,  the
Trust  Administrator's  and  the  Certificateholders'  reliance  on  the  Master
Servicer,  and in a manner  consistent  with the  terms  and  provisions  of any
insurance  policy  required  to be  maintained  by the  Master  Servicer  or any
Servicer  pursuant to this  Agreement  or any  Servicing  Agreement.  The Master
Servicer  acknowledges  that prior to taking certain actions required to service
the  Mortgage  Loans,  each  Servicing  Agreement  provides  that  the  Servicer
thereunder must notify,  consult with, obtain the consent of or otherwise follow
the  instructions  of the Master  Servicer.  The Master  Servicer  is also given
authority  to waive  compliance  by a Servicer  with certain  provisions  of its
Servicing Agreement.  In each such instance,  the Master Servicer shall promptly
instruct such Servicer or otherwise  respond to such Servicer's  request.  In no
event will the Master Servicer  instruct such Servicer to take any action,  give
any consent to action by such Servicer or waive compliance by such Servicer with
any provision of such Servicer's  Servicing Agreement if any resulting action or
failure  to act  would be  inconsistent  with  the  requirements  of the  Rating
Agencies that rated the  Certificates  or would otherwise have an adverse effect
on the Certificateholders.  Any such action or failure to act shall be deemed to
have an adverse  effect on the  Certificateholders  if such action or failure to
act either results in (i) the  downgrading of the rating  assigned by any Rating
Agency  to the  Certificates,  (ii)  the  loss by the  Upper-Tier  REMIC  or the
Lower-Tier  REMIC of REMIC  status for federal  income tax purposes or (iii) the
imposition of any Prohibited  Transaction Tax or any federal taxes on either the
Upper-Tier REMIC, the Lower-Tier REMIC or the Trust Estate.  The Master Servicer
shall have full power and  authority in its sole  discretion  to take any action
with  respect to the Trust  Estate as may be necessary or advisable to avoid the
circumstances  specified  including  clause  (ii)  or  (iii)  of  the  preceding
sentence.

     For the purposes of determining whether any modification of a Mortgage Loan
shall be  permitted  by the Trust  Administrator  or the Master  Servicer,  such
modification  shall be construed as a substitution of the modified Mortgage Loan
for the Mortgage Loan originally  deposited in the Trust Estate if it would be a
"significant  modification"  within the  meaning of Section  1.860G-2(b)  of the
regulations of the U.S.  Department of the Treasury.  No  modification  shall be
approved  unless (i) the modified  Mortgage  Loan would  qualify as a Substitute
Mortgage Loan under Section 2.02 and (ii) with respect to any modification  that
occurs more than three  months after the Closing Date and is not the result of a
default or a reasonably  foreseeable  default under the Mortgage Loan,  there is
delivered  to the Trust  Administrator  an Opinion of Counsel (at the expense of
the  party  seeking  to  modify  the  Mortgage  Loan) to the  effect  that  such
modification  would not be treated as giving rise to a new debt  instrument  for
federal income tax purposes as described in the preceding sentence.

     During the term of this Agreement,  the Master Servicer shall consult fully
with each  Servicer as may be  necessary  from time to time to perform and carry
out  the  Master  Servicer's   obligations   hereunder  and  otherwise  exercise
reasonable  efforts to  encourage  such  Servicer  to perform  and  observe  the
covenants,  obligations  and  conditions to be performed or observed by it under
its Servicing Agreement.

     The  relationship  of the  Master  Servicer  to the  Trustee  and the Trust
Administrator  under this  Agreement is intended by the parties to be that of an
independent contractor and not that of a joint venturer, partner or agent.

     The Master  Servicer  shall  administer  the Trust  Estate on behalf of the
Trustee  and shall have full power and  authority,  acting  alone or (subject to
Section  6.06) through one or more  subcontractors,  to do any and all things in
connection  with such  administration  which it may deem necessary or desirable.
Upon the execution and delivery of this Agreement,  and from time to time as may
be required  thereafter,  the Trust Administrator on behalf of the Trustee shall
furnish the Master  Servicer or its  subcontractors  with any powers of attorney
and such other documents as may be necessary or appropriate to enable the Master
Servicer to carry out its administrative duties hereunder.

     The Seller shall be entitled,  at its option,  to repurchase  any defaulted
Mortgage Loan or any Mortgage Loan as to which default is reasonably foreseeable
from the Trust Estate if, in the Seller's judgment, the default is not likely to
be cured by the Mortgagor;  provided,  however,  that the Cut-Off Date Principal
Balances of the Mortgage Loans repurchased  pursuant to this provision shall not
exceed 2.5% of the Cut-Off  Date  Aggregate  Principal  Balance of the  Mortgage
Loans. The purchase price for any such Mortgage Loan shall be 100% of the unpaid
principal  balance of such  Mortgage Loan plus accrued  interest  thereon at the
Mortgage  Interest  Rate  through  the  last  day of the  month  in  which  such
repurchase occurs.  Upon the receipt of such purchase price, the Master Servicer
shall provide to the Trust  Administrator the certification  required by Section
3.04 and the Trust  Administrator  and the  Custodian,  if any,  shall  promptly
release to the Seller the Owner Mortgage Loan File relating to the Mortgage Loan
being repurchased.

     In the event  that (i) the  Master  Servicer  determines  at any time that,
notwithstanding the representations and warranties set forth in Section 2.03(b),
any Mortgage  Loan is not a "qualified  mortgage"  within the meaning of Section
860G of the  Code  and (ii)  the  Master  Servicer  is  unable  to  enforce  the
obligation of the Seller to purchase such Mortgage Loan pursuant to Section 2.02
within two months of such  determination,  the Master  Servicer shall cause such
Mortgage  Loan to be auctioned  to the highest  bidder and sold out of the Trust
Estate no later than the date 90 days after such determination.  In the event of
any such sale of a Mortgage Loan, the Trust Administrator  shall, at the written
request of the Master Servicer and upon being supported with  appropriate  forms
therefor, within five Business Days of the deposit by the Master Servicer of the
proceeds of such auction into the  Certificate  Account,  release or cause to be
released to the entity  identified  by the Master  Servicer  the  related  Owner
Mortgage Loan File and Servicer Mortgage Loan File and shall execute and deliver
such instruments of transfer or assignment,  in each case without  recourse,  as
shall be necessary to vest in the auction  purchaser  title to the Mortgage Loan
and the Trust Administrator shall have no further  responsibility with regard to
such Owner Mortgage Loan File or Servicer Mortgage Loan File.  Neither the Trust
Administrator,  the Master  Servicer nor any  Servicer,  acting on behalf of the
Trust  Administrator,  shall  provide  financing  from the  Trust  Estate to any
purchaser of a Mortgage Loan.

     The Master Servicer, on behalf of the Trust Administrator,  shall, pursuant
to the Servicing  Agreements,  object to the foreclosure  upon, or other related
conversion of the ownership of, any Mortgaged  Property by the related  Servicer
if (i) the Master Servicer believes such Mortgaged  Property may be contaminated
with or  affected  by  hazardous  wastes or  hazardous  substances  or (ii) such
Servicer does not agree to administer such Mortgaged Property,  once the related
Mortgage  Loan becomes an REO Mortgage  Loan, in a manner which would not result
in a federal tax being imposed upon the Trust Estate or the Upper-Tier  REMIC or
Lower-Tier REMIC.

     The Master  Servicer may enter into a special  servicing  agreement with an
unaffiliated  holder of 100%  Percentage  Interest  of a Class B  Subclass  or a
holder  of  a  class  of  securities  representing  interests  in  the  Class  B
Certificates and/or other subordinated mortgage pass-through certificates,  such
agreement to be substantially in the form of Exhibit M hereto or subject to each
Rating Agency's  acknowledgment  that the ratings of the  Certificates in effect
immediately prior to the entering into of such agreement would not be qualified,
downgraded  or  withdrawn  and the  Certificates  would  not be placed on credit
review status (except for possible upgrading) as a result of such agreement. Any
such  agreement  may contain  provisions  whereby  such holder may  instruct the
Master  Servicer to instruct a Servicer to the extent provided in the applicable
Servicing Agreement to commence or delay foreclosure proceedings with respect to
delinquent Mortgage Loans and will contain provisions for the deposit of cash by
the holder that would be available for  distribution  to  Certificateholders  if
Liquidation Proceeds are less than they otherwise may have been had the Servicer
acted in accordance with its normal procedures.

Section 3.09.     Termination and Substitution of Servicing
Agreements.

     Upon the  occurrence  of any event for which a Servicer  may be  terminated
pursuant to its Servicing Agreement,  the Master Servicer shall promptly deliver
to the Seller, the Trust Administrator and the Trustee an Officer's  Certificate
certifying  that an event has  occurred  which may justify  termination  of such
Servicing  Agreement,  describing the  circumstances  surrounding such event and
recommending  what action  should be taken by the Trustee  with  respect to such
Servicer.  If the Master Servicer  recommends  that such Servicing  Agreement be
terminated,  the Master Servicer's  certification  must state that the breach is
material  and not merely  technical  in nature.  Upon  written  direction of the
Master  Servicer,  based upon such  certification,  the Trustee  shall  promptly
terminate such Servicing Agreement.  Notwithstanding the foregoing, in the event
that (i) Norwest  Mortgage fails to make any advance,  as a consequence of which
the Trust Administrator is obligated to make an advance pursuant to Section 3.03
and (ii) the Trust Administrator provides Norwest Mortgage written notice of the
failure to make such advance and such failure shall  continue  unremedied  for a
period of 15 days after receipt of such notice,  the Trust  Administrator  shall
recommend  to the Trustee the  termination  of the Norwest  Servicing  Agreement
without the  recommendation of the Master Servicer and upon such  recommendation
the Trustee shall terminate the Norwest Servicing Agreement. The Master Servicer
shall indemnify the Trustee and the Trust  Administrator  and hold each harmless
from and against any and all claims, liabilities, costs and expenses (including,
without  limitation,  reasonable  attorneys'  fees)  arising out of, or assessed
against the Trustee or the Trust Administrator in connection with termination of
such Servicing  Agreement at the direction of the Master Servicer.  In addition,
the Master  Servicer  shall  indemnify the Trustee and hold it harmless from and
against any and all claims, liabilities,  costs and expenses (including, without
limitation,  reasonable attorneys' fees) arising out of, or assessed against the
Trustee in connection with the termination of the Norwest Servicing Agreement as
provided  in the second  preceding  sentence.  If the  Trustee  terminates  such
Servicing Agreement, the Trustee may enter into a substitute Servicing Agreement
with the Master Servicer or, at the Master Servicer's  nomination,  with another
mortgage   loan  service   company   acceptable   to  the  Trustee,   the  Trust
Administrator, the Master Servicer and each Rating Agency under which the Master
Servicer or such substitute servicer, as the case may be, shall assume, satisfy,
perform and carry out all liabilities,  duties, responsibilities and obligations
that are to be, or otherwise were to have been, satisfied, performed and carried
out by such Servicer under such terminated Servicing Agreement.  Until such time
as the Trustee enters into a substitute  servicing agreement with respect to the
Mortgage Loans previously  serviced by such Servicer,  the Master Servicer shall
assume,  satisfy,  perform and carry out all obligations which otherwise were to
have been  satisfied,  performed  and  carried  out by such  Servicer  under its
terminated Servicing  Agreement.  However, in no event shall the Master Servicer
be deemed to have assumed the  obligations of a Servicer to advance  payments of
principal  and  interest on a delinquent  Mortgage  Loan in excess of the Master
Servicer's  independent  Periodic Advance  obligation under Section 3.03 of this
Agreement.  As compensation for the Master Servicer of any servicing obligations
fulfilled  or assumed  by the Master  Servicer,  the  Master  Servicer  shall be
entitled  to any  servicing  compensation  to which a  Servicer  would have been
entitled if the Servicing Agreement with such Servicer had not been terminated.

Section 3.10.     1934 Act Reports.

     The  Master  Servicer  shall,  on behalf of the  Seller,  make all  filings
required  to be made by the  Seller  with  respect  to the Class A  Certificates
(other  than  the  Class  A-WIO  and  Class  A-PO  Certificates),  the  Class  M
Certificates  and the  Class  B-1 and Class  B-2  Certificates  pursuant  to the
Securities Exchange Act of 1934, as amended.

to no  further  distributions  of  principal  or  interest  (including,  without

     With  respect  to any  Distribution  Date,  the  amount  of  the  Principal

     (ii)Distributions  on the  Uncertificated  Lower-Tier  Interests.  On  each
Distribution  Date,  each  Uncertificated   Lower-Tier  Interest  shall  receive
distributions  in  respect  of  principal  in an amount  equal to the  amount of
principal  distributed  to its  respective  Corresponding  Upper-Tier  Class  or
Classes as provided  herein.  On each  Distribution  Date,  each  Uncertificated
Lower-Tier  Interest  shall receive  distributions  in respect of interest in an
amount  equal to the (i) Class A Subclass  Interest  Accrual  Amount and Class A
Subclass Unpaid  Interest  Shortfall,  (ii) Class M Interest  Accrual Amount and
Class M Unpaid  Interest  Shortfall or (iii) Class B Subclass  Interest  Accrual
Amount and Class B Subclass  Unpaid Interest  Shortfall,  as the case may be, in
respect of its  Corresponding  Upper-Tier Class or Classes,  in each case to the
extent  actually  distributed.  Such amounts  distributed to the  Uncertificated
Lower-Tier  Interests in respect of principal  and interest  with respect to any
Distribution  Date  are  referred  to  herein  collectively  as the  "Lower-Tier
Distribution Amount."

     As of any date,  the principal  balance of each  Uncertificated  Lower-Tier
Interest  (other  than the Class  A-LIO  Interest)  equals  the Class A Subclass
Principal  Balances,  Class M  Principal  Balance or Class B Subclass  Principal
Balances, as the case may be, of the respective  Corresponding  Upper-Tier Class
or Classes.  The Class A-LIO  Interest  has no principal  balance.  The notional
amount  of  the  Class  A-LIO  Interest   equals  the  notional  amount  of  its
Corresponding Upper-Tier Class or Classes. The initial principal balance of each
Uncertificated  Lower-Tier Interest (other than the Class A-LIO Interest) equals
the Original  Class A Subclass  Principal  Balances,  Original Class M Principal
Balance,  Original  Class B-1 Principal  Balance,  Original  Class B-2 Principal
Balance,  Original  Class B-3 Principal  Balance,  Original  Class B-4 Principal
Balance or  Original  Class B-5  Principal  Balance,  as the case may be, of the
respective  Corresponding  Upper-Tier  Class or Classes.  The  initial  notional
amount of the Class A-LIO  Interest  equals the initial  notional  amount of its
Corresponding Upper-Tier Class or Classes.

     The  pass-through  rate  with  respect  to each  Uncertificated  Lower-Tier
Interest (other than the Class A-L2 Interest,  Class A-L9 Interest,  Class A-LIO
Interest and Class A-LPO Interest) shall be 7.250% per annum.  The  pass-through
rate with  respect to the Class  A-L2  Interest  shall be 9.000% per annum.  The
pass-through  rate with respect to the Class A-L9  Interest  shall be 7.000% per
annum. The  pass-through  rate with respect to the Class A-LIO Interest shall be
the Class A-WIO  Pass-Through Rate. The Class A-LPO Interest is a principal-only
interest and is not entitled to  distributions  of interest.  Any  Non-Supported
Interest Shortfalls will be allocated to each Uncertificated Lower-Tier Interest
in the same relative proportions as interest is allocated to such Uncertificated
Lower-Tier Interest.

     (b)  The  Class  A-3  and  Class  A-WIO   Certificates  are   interest-only
Certificates and are not entitled to distributions in respect of principal.

     On each Distribution Date occurring prior to the Cross-Over Date, the Class
A Non-PO Principal  Distribution  Amount will be allocated among and distributed
in reduction of the Class A Subclass  Principal  Balances of the  Subclasses  of
Class A Certificates  (other than the Class A Subclass  Principal Balance of the
Class A-PO Certificates) as follows:

     first,  concurrently,  as  follows,  up to the  Priority  Amount  for  such
Distribution Date:

     (i)  22.0000000000%,  sequentially,  to the Class A-6  Certificates and the
Class A-7 A  Component,  in that  order,  until the Class A  Subclass  Principal
Balance of the Class A-6 Certificates and the Component Principal Balance of the
Class A-7 A Component have been reduced to zero; and

     (ii)  78.0000000000%  to the  Class  A-8  Certificates,  until  the Class A
Subclass Principal Balance thereof has been reduced to zero;

     second,  concurrently,  to the Class A-R and Class A-LR  Certificates,  pro
rata,  until the Class A Subclass  Principal  Balance of each such  Subclass has
been reduced to zero;

     third, concurrently, as follows:

     (i)  16.6613244439%  to the  Class  A-1  Certificates,  until  the  Class A
Subclass Principal Balance thereof has been reduced to zero;

     (ii)  10.4173344445%  to the  Class  A-2  Certificates,  until  the Class A
Subclass Principal Balance thereof has been reduced to zero; and

     (iii)  72.9213411116%  to the  Class  A-9  Certificates,  until the Class A
Subclass Principal Balance thereof has been reduced to zero;

     fourth, to the Class A-4 Certificates, until the Class A Subclass Principal
Balance thereof has been reduced to zero;

     fifth, to the Class A-5 Certificates,  until the Class A Subclass Principal
Balance thereof has been reduced to zero;

     sixth, to the Class A-7 B Component,  until the Component Principal Balance
thereof has been reduced to zero; and

     seventh,  concurrently,  as follows,  without regard to the Priority Amount
for such Distribution Date:

     (i)  22.0000000000%,  sequentially,  to the Class A-6  Certificates and the
Class A-7 A  Component,  in that  order,  until the Class A  Subclass  Principal
Balance of the Class A-6 Certificates and the Component Principal Balance of the
Class A-7 A Component have been reduced to zero; and

     (ii)  78.0000000000%  to the  Class  A-8  Certificates,  until  the Class A
Subclass Principal Balance thereof has been reduced to zero.

     (c) Notwithstanding  the foregoing,  on each Distribution Date occurring on
or subsequent to the Cross-Over Date, the Class A Non-PO Principal  Distribution
Amount shall be distributed among the Subclasses of Class A Certificates  (other
than the Class A-PO  Certificates) pro rata in accordance with their outstanding
Class A Subclass  Principal Balances without regard to either the proportions or
the priorities set forth in Section 4.01(b).

     (d) (i) For  purposes  of  determining  whether the  Subclasses  of Class B
Certificates are eligible to receive  distributions of principal with respect to
any Distribution Date, the following tests shall apply:

          (A) if the  Current  Class M  Fractional  Interest  is less  than  the
     Original Class M Fractional  Interest and the Class M Principal  Balance is
     greater than zero, the Class B-1, Class B-2, Class B-3, Class B-4 and Class
     B-5  Certificates  shall  not  be  eligible  to  receive  distributions  of
     principal; or

          (B) if the  Current  Class B-1  Fractional  Interest  is less than the
     Original Class B-1 Fractional  Interest and the Class B-1 Principal Balance
     is greater  than zero,  the Class B-2,  Class B-3,  Class B-4 and Class B-5
     Certificates  shall not be eligible to receive  distributions of principal;
     or

          (C) if the  Current  Class B-2  Fractional  Interest  is less than the
     Original Class B-2 Fractional  Interest and the Class B-2 Principal Balance
     is greater than zero, the Class B-3,  Class B-4 and Class B-5  Certificates
     shall not be eligible to receive distributions of principal; or

          (D) if the  Current  Class B-3  Fractional  Interest  is less than the
     Original Class B-3 Fractional  Interest and the Class B-3 Principal Balance
     is greater than zero, the Class B-4 and Class B-5 Certificates shall not be
     eligible to receive distributions of principal; or

          (E) if the  Current  Class B-4  Fractional  Interest  is less than the
     Original Class B-4 Fractional  Interest and the Class B-4 Principal Balance
     is greater than zero, the Class B-5  Certificates  shall not be eligible to
     receive distributions of principal.

     (ii)Notwithstanding   the  foregoing,  if  on  any  Distribution  Date  the
aggregate  distributions  to  Holders  of the Class M  Certificates  and/or  the
Subclasses  of  Class  B  Certificates  entitled  to  receive  distributions  of
principal would reduce the Class M Principal Balance and/or the Class B Subclass
Principal Balances of the Subclasses of Class B Certificates entitled to receive
distributions of principal below zero,  first the Class M Prepayment  Percentage
and/or  the Class B  Subclass  Prepayment  Percentage  of any  affected  Class B
Subclass for such  Distribution  Date beginning with the affected  Subclass with
the lowest numerical  Subclass  designation and then, if necessary,  the Class M
Percentage and/or the Class B Subclass  Percentage of such Subclass of the Class
B  Certificates  for such  Distribution  Date shall be reduced to the respective
percentages  necessary to bring the Class M Principal Balance and/or the Class B
Subclass  Principal  Balance  of such  Class B  Subclass  to zero.  The  Class B
Subclass  Prepayment  Percentages  and the Class B Subclass  Percentages  of the
remaining   Class  B  Subclasses  will  be  recomputed   substituting   for  the
Subordinated   Prepayment   Percentage  and  Subordinated   Percentage  in  such
computations the difference between (A) the Subordinated  Prepayment  Percentage
or  Subordinated  Percentage,  as the  case  may be,  and  (B)  the  percentages
determined in  accordance  with the  preceding  sentence  necessary to bring the
Class M Principal Balance and/or the Class B Subclass  Principal Balances of the
affected  Class B Subclasses  to zero;  provided,  however,  that if the Class B
Subclass  Principal  Balances of all the Class B Subclasses  eligible to receive
distributions of principal shall be reduced to zero on such  Distribution  Date,
the Class B Subclass  Prepayment  Percentage and the Class B Subclass Percentage
of the Class B Subclass with the lowest  numerical  Subclass  designation  which
would  otherwise  be  ineligible  to  receive   distributions  of  principal  in
accordance  with this  Section  shall equal the  remainder  of the  Subordinated
Prepayment  Percentage for such  Distribution  Date minus the sum of the Class M
Prepayment  Percentage  and the Class B Subclass  Prepayment  Percentages of the
Class B Subclasses having lower numerical Subclass designations, if any, and the
remainder of the Subordinated  Percentage for such  Distribution  Date minus the
sum of the Class M Percentage and the Class B Subclass  Percentages of the Class
B Subclasses having lower numerical Subclass designations, if any, respectively.
Any entitlement of any Class B Subclass to principal payments solely pursuant to
this clause (ii) shall not cause such Subclass to be regarded as being  eligible
to receive principal distributions for the purpose of applying the definition of
its Class B Subclass Percentage or Class B Subclass Prepayment Percentage.

     (e) The Trust  Administrator  shall  establish and maintain the  Upper-Tier
Certificate  Account,  which shall be a separate  trust  account and an Eligible
Account.  On each Distribution  Date other than the Final  Distribution Date (if
such Final  Distribution  Date is in connection with a purchase of the assets of
the Trust Estate by the Seller), the Paying Agent shall, on behalf of the Master
Servicer,  from funds available on deposit in the Payment Account,  (i) deposit,
in  immediately  available  funds,  by wire  transfer  or  otherwise,  into  the
Upper-Tier  Certificate  Account  the  Lower-Tier  Distribution  Amount and (ii)
distribute  to the Class  A-LR  Certificateholder  (other  than as  provided  in
Section 9.01 respecting the final distribution to  Certificateholders)  by check
mailed to such Holder at the address of such Holder appearing in the Certificate
Register,  the Class A Subclass  Distribution  Amount with  respect to the Class
A-LR  Certificate  and  all  other  amounts  distributable  to  the  Class  A-LR
Certificate.  The Trust  Administrator  may clear and terminate  the  Upper-Tier
Certificate Account pursuant to Section 9.01.

     (f) On each  Distribution  Date other than the Final  Distribution Date (if
such Final  Distribution  Date is in connection with a purchase of the assets of
the Trust Estate by the Seller), the Paying Agent shall, on behalf of the Master
Servicer,  from funds remitted to it by the Master Servicer,  distribute to each
Certificateholder of record (other than the Class A-LR Certificateholder) on the
preceding  Record Date (other than as provided in Section  9.01  respecting  the
final  distribution  to  Certificateholders  or in the  last  paragraph  of this
Section  4.01(f)  respecting the final  distribution  in respect of any Class or
Subclass) either in immediately  available funds by wire transfer to the account
of  such  Certificateholder  at  a  bank  or  other  entity  having  appropriate
facilities  therefor,  if such  Certificateholder  holds  Certificates  having a
Denomination  at least  equal to that  specified  in Section  11.26,  and has so
notified the Master Servicer or, if applicable,  the Paying Agent at least seven
Business  Days  prior  to  the  Distribution  Date  or,  if  such  Holder  holds
Certificates  having,  in the aggregate,  a Denomination less than the requisite
minimum  Denomination  or if such Holder holds the Class A-R  Certificate or has
not so notified the Paying Agent,  by check mailed to such Holder at the address
of such Holder appearing in the Certificate Register, such Holder's share (based
on, with respect to each Class or  Subclass,  the  aggregate  of the  Percentage
Interests  represented by  Certificates  of the applicable  Class or Subclass of
Certificates  held by such  Holder of the Class A Subclass  Distribution  Amount
with respect to each Subclass of Class A Certificates,  the Class M Distribution
Amount  with  respect  to the  Class M  Certificates  and the  Class B  Subclass
Distribution Amount with respect to each such Subclass of Class B Certificates.

     In the event that, on any Distribution Date prior to the Final Distribution
Date,  the  Class A  Subclass  Principal  Balance  of any  Subclass  of  Class A
Certificates  (other  than  the  Class  A-3,  Class  A-WIO,  Class  A-R or  A-LR
Certificates),  the Class M Principal Balance of the Class M Certificates or the
Class B Subclass Principal Balance of any Subclass of Class B Certificates would
be reduced  to zero,  in the case of the Class A-3  Certificates,  the Class A-3
Notional  Amount  would be  reduced to zero,  or in the case of the Class  A-WIO
Certificates,  the Class A-WIO  Notional  Amount  would be reduced to zero,  the
Master  Servicer  shall,  as soon as practicable  after the  Determination  Date
relating to such  Distribution  Date, send a notice to the Trust  Administrator.
The Trust  Administrator  will then send a notice to each  Certificateholder  of
such Class or Subclass with a copy to the Certificate Registrar, specifying that
the final  distribution  with respect to such Class or Subclass  will be made on
such  Distribution  Date  only  upon  the  presentation  and  surrender  of such
Certificateholder's   Certificates   at  the  office  or  agency  of  the  Trust
Administrator  therein specified;  provided,  however,  that the failure to give
such notice  will not entitle a  Certificateholder  to any  interest  beyond the
interest  payable  with respect to such  Distribution  Date in  accordance  with
Section 4.01(a)(i).

     (g) The  Paying  Agent (or if no Paying  Agent is  appointed  by the Master
Servicer,  the Master  Servicer)  shall  withhold or cause to be  withheld  such
amounts as may be required  by the Code  (giving  full effect to any  exemptions
from  withholding  and  related  certifications  required  to  be  furnished  by
Certificateholders  and any reductions to withholding by virtue of any bilateral
tax  treaties  and any  applicable  certification  required to be  furnished  by
Certificateholders  with  respect  thereto)  from  distributions  to be  made to
persons other than U.S. Persons ("Non-U.S.  Persons"). Amounts withheld pursuant
to this  Section  4.01(g)  shall be treated as having  been  distributed  to the
related  Certificateholder for all purposes of this Agreement.  For the purposes
of this  paragraph,  a "U.S.  Person"  is a citizen  or  resident  of the United
States, a corporation,  partnership (except to the extent provided in applicable
Treasury  regulations) or other entity created or organized in or under the laws
of the United States or any  political  subdivision  thereof,  an estate that is
subject to United  States  federal  income tax  regardless  of the source of its
income or a trust if (i) for taxable years beginning after December 31, 1996 (or
for taxable  years  ending  after  August 20,  1996,  if the trustee has made an
applicable  election),  a court  within  the United  States is able to  exercise
primary  supervision over the administration of such trust, and one or more such
U.S.  Persons have the  authority to control all  substantial  decisions of such
trust or (ii) for all other  taxable  years,  such  trust is  subject  to United
States  federal  income tax  regardless  of the source of its income (or, to the
extent provided in applicable Treasury regulations,  certain trusts in existence
on August 20, 1996 which are eligible to elect to be treated as U.S. Persons).

Section 4.02.     Allocation of Realized Losses.

     (a) With  respect  to any  Distribution  Date,  the  principal  portion  of
Realized  Losses  (other than Debt Service  Reductions,  Excess  Special  Hazard
Losses,  Excess Fraud Losses and Excess Bankruptcy  Losses) will be allocated as
follows:

     first, to the Class B-5 Certificates  until the Class B-5 Principal Balance
has been reduced to zero;

     second, to the Class B-4 Certificates until the Class B-4 Principal Balance
has been reduced to zero;

     third, to the Class B-3 Certificates  until the Class B-3 Principal Balance
has been reduced to zero;

     fourth, to the Class B-2 Certificates until the Class B-2 Principal Balance
has been reduced to zero;

     fifth, to the Class B-1 Certificates  until the Class B-1 Principal Balance
has been reduced to zero;

     sixth, to the Class M Certificates  until the Class M Principal Balance has
been reduced to zero; and

     seventh,  concurrently,  to the Class A Certificates  (other than the Class
A-PO  Certificates) and Class A-PO  Certificates,  pro rata, based on the Non-PO
Fraction and the PO Fraction, respectively.

     This allocation of Realized  Losses will be effected  through the reduction
of the applicable Class's or Subclass's Principal Balance.

     (b) With respect to any Distribution  Date, the principal portion of Excess
Special  Hazard  Losses,  Excess  Fraud  Losses  and  Excess  Bankruptcy  Losses
occurring  with  respect  to any  Mortgage  Loan  allocable  to the  Class  A-PO
Certificates will equal the product of the amount of any such principal loss and
the PO Fraction for such  Mortgage  Loan.  The  principal  portion of any Excess
Special  Hazard  Losses,  Excess  Fraud  Losses  and  Excess  Bankruptcy  Losses
remaining after allocation to the Class A-PO Certificates in accordance with the
preceding  sentence  shall be allocated pro rata among the Class A  Certificates
(other  than the Class  A-PO  Certificates),  Class M  Certificates  and Class B
Certificates  based on the Class A Non-PO Principal  Balance,  Class M Principal
Balance and the Class B Principal Balance, respectively. Any such loss allocated
to the Class A Certificates  shall be allocated on the subsequent  Determination
Date among the  outstanding  Subclasses of Class A Certificates  (other than the
Class A-7 and Class A-PO  Certificates)  and Class A-7  Components in accordance
with the Class A Subclass Loss  Percentages and Component Loss Percentages as of
such  Determination  Date.  Any such loss  allocated to the Class B Certificates
shall  be  allocated  pro  rata  among  the  outstanding  Subclasses  of Class B
Certificates based on their Class B Subclass Principal Balances.

     (c) Any Realized Losses  allocated to a Subclass of Class A Certificates or
Class B Certificates or to the Class M Certificates  pursuant to Section 4.02(a)
or Section 4.02(b) shall be allocated among the Certificates of such Subclass or
Class based on their Percentage Interests.

     (d) In the event  that  there is a  Recovery  of an amount  in  respect  of
principal of a Mortgage Loan which had  previously  been allocated as a Realized
Loss to any Subclasses of Class A Certificates,  the Class M Certificates or any
Subclasses of Class B Certificates,  each outstanding Class or Subclass to which
such Realized Loss had previously  been allocated shall be entitled to its share
(with respect to the Class A-PO  Certificates,  based on the PO Fraction of such
Mortgage  Loan and,  with  respect to the Class A  Certificates  (other than the
Class A-PO Certificates),  Class M Certificates and Class B Certificates,  based
on their pro rata share of the Non-PO  Fraction of such  Mortgage  Loan) of such
Recovery up to the amount of such  Realized  Loss  previously  allocated to such
Class or Subclass on the  Distribution  Date in the month following the month in
which  such  recovery  is  received.  When the  Principal  Balance of a Class or
Subclass of Certificates  has been reduced to zero, such Class or Subclass shall
not be entitled to any share of such  Recovery.  In the event that the amount of
such recovery exceeds the amount of such Recovery  allocated to each outstanding
Class or Subclass in accordance with the preceding provisions,  each outstanding
Class  or  Subclass  shall be  entitled  to its pro rata  share  (determined  as
described  above) of such  excess up to the amount of any  unrecovered  Realized
Loss  previously  allocated  to such  Class  or  Subclass.  Notwithstanding  the
foregoing  provisions,  but subject to the following  proviso,  if such Recovery
occurs within two years of the realization of such loss and (i) is the result of
an event that would have given rise to the  repurchase  of the related  Mortgage
Loan by the Seller pursuant to Section 2.02 or 2.03, or (ii) represents in whole
or part  funds  which the  applicable  Servicer  had  received  in  respect of a
Liquidated  Loan but failed to remit to the  Certificate  Account on or prior to
the Business Day  preceding  the  Distribution  Date  following  the  Applicable
Unscheduled  Principal  Receipt  Period  in which  the  Mortgage  Loan  became a
Liquidated  Loan  such  Recovery  may,  at the  sole  discretion  of the  Master
Servicer,  be treated as a repurchase or an Unscheduled  Principal  Receipt with
respect to such Mortgage Loan, as the case may be, the Realized Loss  previously
recognized may be reversed and treated for all subsequent  purposes as if it had
never occurred and the Master Servicer may make such  adjustments to interest or
principal distributions on the Certificates and to the principal balances of the
Certificates  as the  Master  Servicer  in its  good  faith  judgment  and  sole
discretion  deems  necessary  or  desirable  to  effectuate  the reversal of the
Realized  Loss  and  the  treatment  of such  amount  as a  repurchase  or as an
Unscheduled Principal Receipt, as the case may be; provided that such actions do
not  result in the  aggregate  distributions  made in  respect of each Class and
Subclass of Certificates  whose principal  balances were previously reduced as a
result of such Realized  Loss being less than such Class or Subclass  would have
received if such Recovery had been  deposited in the  Certificate  Account on or
prior  to the  Business  Day  preceding  the  Distribution  Date  following  the
Applicable  Unscheduled  Principal  Receipt  Period in which the  Mortgage  Loan
became a Liquidated Loan.

     (e) The interest  portion of Excess  Special  Hazard  Losses,  Excess Fraud
Losses  and  Excess  Bankruptcy  Losses  shall be  allocated  among  the Class A
Certificates,  Class M Certificates and Class B Certificates,  pro rata based on
the Class A Interest Accrual Amount, the Class M Interest Accrual Amount and the
Class B Interest  Accrual  Amount for the  related  Distribution  Date,  without
regard to any reduction  pursuant to this  sentence.  Any such loss allocated to
the Class A Certificates shall be allocated among the outstanding  Subclasses of
Class A Certificates based on their Class A Subclass Interest  Percentages.  Any
such loss  allocated to the Class B  Certificates  will be  allocated  among the
outstanding  Subclasses of Class B Certificates  based on their Class B Subclass
Interest Percentages.  In addition,  after the Class M Principal Balance and the
Class B Principal  Balance  have been reduced to zero,  the interest  portion of
Realized  Losses (other than Excess Special  Hazard Losses,  Excess Fraud Losses
and Excess Bankruptcy Losses) will be allocated among the outstanding Subclasses
of Class A Certificates based on their Class A Subclass Interest Percentages.

     (f) Realized Losses  allocated in accordance with this Section 4.02 will be
allocated on the  Determination  Date in the second month following the month in
which such loss was incurred with respect to the preceding Distribution Date.

     (g) With  respect  to any  Distribution  Date,  the  principal  portion  of
Realized  Losses and recoveries  attributable to previously  allocated  Realized
Losses  allocated  pursuant  to this  Section  4.02  will be  allocated  to each
Uncertificated Lower-Tier Interest in an amount equal to the amount allocated to
its respective Corresponding Upper-Tier Class or Classes as provided above.

     With respect to any  Distribution  Date,  the interest  portion of Realized
Losses  allocated  pursuant  to this  Section  4.02  will be  allocated  to each
Uncertificated  Lower-Tier Interest in the same relative proportions as interest
is allocated to such Uncertificated Lower-Tier Interest.

Section 4.03.     Paying Agent.

     (a) The Master Servicer hereby appoints the Trust  Administrator as initial
Paying  Agent to make  distributions  to  Certificateholders  and to  forward to
Certificateholders the periodic statements and the annual statements required by
Section 4.04 as agent of the Master Servicer.

     The Master Servicer may, at any time, remove or replace the Paying Agent.

     The Master  Servicer  shall  cause any  Paying  Agent that is not the Trust
Administrator to execute and deliver to the Trust Administrator an instrument in
which such Paying  Agent  agrees with the Trust  Administrator  that such Paying
Agent shall:

          (i)  hold  all  amounts  remitted  to it by the  Master  Servicer  for
     distribution   to   Certificateholders   in  trust  for  the   benefit   of
     Certificateholders until such amounts are distributed to Certificateholders
     or otherwise disposed of as herein provided;

          (ii) give the Trust Administrator  notice of any default by the Master
     Servicer in remitting any required amount; and

          (iii) at any time during the continuance of any such default, upon the
     written  request  of the Trust  Administrator,  forthwith  pay to the Trust
     Administrator all amounts held in trust by such Paying Agent.

     (b) The Paying Agent shall establish and maintain a Payment Account,  which
shall be a separate trust account and an Eligible  Account,  in which the Master
Servicer shall cause to be deposited from funds in the  Certificate  Account or,
to the  extent  required  hereunder,  from its own funds (i) at or before  10:00
a.m.,  New York time, on the Business Day preceding each  Distribution  Date, by
wire transfer of  immediately  available  funds,  any Periodic  Advance for such
Distribution  Date,  pursuant to Section  3.03 and (ii) at or before 10:00 a.m.,
New York time, on the Business Day  preceding  each  Distribution  Date, by wire
transfer  of  immediately  available  funds,  (a) an  amount  equal  to the Pool
Distribution  Amount, (b) Net Foreclosure  Profits, if any, with respect to such
Distribution  Date and (c) the amount of any  recovery  in respect of a Realized
Loss. The Master  Servicer may cause the Paying Agent to invest the funds in the
Payment  Account.  Any such investment shall be in Eligible  Investments,  which
shall mature not later than the Business Day preceding the related  Distribution
Date   (unless  the  Eligible   Investments   are   obligations   of  the  Trust
Administrator,  in which case such Eligible  Investments  shall mature not later
than the  Distribution  Date),  and  shall not be sold or  disposed  of prior to
maturity. All income and gain realized from any such investment shall be for the
benefit of the Master  Servicer and shall be subject to its  withdrawal or order
from time to time.  The  amount of any  losses  incurred  in respect of any such
investments shall be deposited in the Payment Account by the Master Servicer out
of its own funds immediately as realized. The Paying Agent may withdraw from the
Payment  Account  any  amount  deposited  in the  Payment  Account  that was not
required to be deposited therein and may clear and terminate the Payment Account
pursuant to Section 9.01.

Section 4.04.     Statements to Certificateholders;
Report to the Trust Administrator and the Seller.

     Concurrently with each distribution pursuant to Section 4.01(f), the Master
Servicer,  or the Paying Agent appointed by the Master Servicer (upon receipt of
such statement from the Master Servicer), shall forward or cause to be forwarded
by mail to each  Holder of a  Certificate  and the  Seller a  statement  setting
forth:

          (i) the  amount  of  such  distribution  to  Holders  of each  Class A
     Subclass  allocable to  principal,  separately  identifying  the  aggregate
     amount of any Unscheduled Principal Receipts included therein;

          (ii) (a) the amount of such  distribution  to Holders of each Subclass
     of Class A  Certificates  allocable  to  interest,  (b) the  amount  of the
     Current  Class A Interest  Distribution  Amount  allocated  to each Class A
     Subclass,  (c) any Class A Subclass Interest Shortfall Amounts arising with
     respect to such Distribution Date and any remaining Class A Subclass Unpaid
     Interest  Shortfall  with respect to each  Subclass  after giving effect to
     such distribution,  (d) the amount of any Non-Supported  Interest Shortfall
     allocated to each Class A Subclass for such  Distribution  Date and (e) the
     interest  portion of Excess Special Hazard Losses,  Excess Fraud Losses and
     Excess  Bankruptcy  Losses allocated to each Subclass for such Distribution
     Date;

          (iii)  the  amount  of such  distribution  to  Holders  of the Class M
     Certificates  allocable to principal,  identifying the aggregate  amount of
     any Unscheduled Principal Receipts included therein;

          (iv) (a) the  amount of such  distribution  to  Holders of the Class M
     Certificates  allocable to interest,  (b) the amount of the Current Class M
     Interest  Distribution  Amount,  (c) any Class M Interest  Shortfall Amount
     arising with respect to such  Distribution  Date and any remaining  Class M
     Unpaid Interest Shortfall after giving effect to such distribution, (d) the
     amount of any  Non-Supported  Interest  Shortfall  allocated to the Class M

who shall provide copies thereof to Persons making written  request  therefor at
the Corporate Trust Office.

     In the case of information  furnished with respect to a Subclass of Class A
Certificates  pursuant  to  clauses  (i)  and  (ii)  above,  with  the  Class  M

and as a dollar amount per Class A-WIO Certificate with a 1% Denomination.

     Within a reasonable period of time after the end of each calendar year, the
Master Servicer shall furnish or cause to be furnished to each Person who at any
time  during the  calendar  year was the  Holder of a  Certificate  a  statement
containing  the  information  set forth in clauses (i) and (ii)(a)  above in the
case of a Class A Certificateholder,  the information set forth in clauses (iii)
and (iv)(a) above in the case of a Class M Certificateholder and the information
contained  in  clauses  (v)  and  (vi)(a)  above  in  the  case  of  a  Class  B
Certificateholder  aggregated  for  such  calendar  year or  applicable  portion

Master  Servicer  shall be deemed  to have been  satisfied  to the  extent  that
substantially  comparable  information  shall be provided by the Master Servicer
pursuant to any requirements of the Code from time to time in force.

     Prior to the close of business on the third  Business  Day  preceding  each
Distribution  Date,  the Master  Servicer shall furnish a statement to the Trust
Administrator,  any  Paying  Agent  and  the  Seller  (the  information  in such
statement to be made available to  Certificateholders  by the Master Servicer on
written  request)  setting forth the Class A Subclass  Distribution  Amount with
respect to each Class A Subclass,  the Class M Distribution Amount and the Class
B Subclass  Distribution  Amount  with  respect to each  Class B  Subclass.  The
determination  by the Master  Servicer of such amounts shall,  in the absence of
obvious error, be presumptively  deemed to be correct for all purposes hereunder
and the Trust  Administrator  and the Paying Agent shall be protected in relying
upon the same without any independent check or verification.

     In addition to the reports  required  pursuant to this  Section  4.04,  the
Master  Servicer  shall make  available  upon  request  to each  Holder and each
proposed  transferee of a Class A-WIO, Class A-PO, Class B-3, Class B-4 or Class
B-5  Certificate  such  additional  information,  if any,  as may be required to
permit the proposed transfer to be effected pursuant to Rule 144A.

Section 4.05.     Reports to Mortgagors and the Internal Revenue
Service.

     The Master  Servicer  shall, in each year beginning after the Cut-Off Date,
make the reports of foreclosures and  abandonments of any Mortgaged  Property as
required by Code Section 6050J. In order to facilitate  this reporting  process,
the Master Servicer shall request that each Servicer,  on or before January 15th
of each year, shall provide to the Internal Revenue Service,  with copies to the
Master Servicer, reports relating to each instance occurring during the previous
calendar  year in which such  Servicer (i) on behalf of the Trust  Administrator
acquires  an  interest  in a Mortgaged  Property  through  foreclosure  or other
comparable  conversion  in full  or  partial  satisfaction  of a  Mortgage  Loan
serviced by such Servicer,  or (ii) knows or has reason to know that a Mortgaged
Property has been  abandoned.  Reports from the  Servicers  shall be in form and
substance sufficient to meet the reporting  requirements imposed by Code Section
6050J.  In  addition,  each  Servicer  shall  provide the Master  Servicer  with
sufficient  information  to allow the Master  Servicer  to, for each year ending
after the  Cut-Off  Date,  provide,  or cause to be  provided,  to the  Internal
Revenue  Service and the Mortgagors  such  information as is required under Code
Sections 6050H (regarding payment of interest) and 6050P (regarding cancellation
of indebtedness).

Section 4.06      Calculation of Amounts; Binding Effect of
Interpretations and Actions of Master Servicer.

                  The  Master   Servicer   will   compute   the  amount  of  all
distributions  to be made on the  Certificates and all losses to be allocated to
the  Certificates.  In the event that the  Master  Servicer  concludes  that any
ambiguity or uncertainty  exists in any provisions of this Agreement relating to
distributions  to be made on the Certificates or the allocation of losses to the
Certificates, the interpretation of such provisions and any actions taken by the
Master Servicer in good faith to implement such interpretation  shall be binding
upon Certificateholders.

Section 4.07.  Determination of LIBOR.

     On each Rate Determination  Date, the Trust  Administrator  shall determine
LIBOR for the succeeding LIBOR Based Interest Accrual Period on the basis of the
offered  LIBOR  quotations of the Reference  Banks (as defined  below),  as such
quotations  are  provided to the Trust  Administrator  as of 11:00 a.m.  (London
time) on such Rate  Determination  Date.  As used herein with  respect to a Rate
Determination  Date,  "Reference  Banks"  means four  leading  banks  engaged in
transactions in Eurodollar deposits in the international Eurocurrency market (i)
with an established place of business in London, (ii) whose quotations appear on
the Reuters  Screen  LIBO Page on the Rate  Determination  Date in question  and
(iii) which have been designated as such by the Trust Administrator and are able
and willing to provide such quotations to the Trust  Administrator  on each Rate
Determination  Date; and "Reuters Screen LIBO Page" means the display designated
as page "LIBO" on the Reuters Monitor Money Rates Service (or such other page as
may replace the LIBO page on that service for the purpose of  displaying  London
interbank offered rate quotations of major banks). If a Reference Bank should be
removed from the Reuters  Screen LIBO Page or in any other way fails to meet the
qualifications  of a Reference  Bank, the Trust  Administrator  may, in its sole
discretion, designate an alternative Reference Bank.

     On each Rate  Determination  Date, LIBOR for the  Distribution  Date in the
succeeding months will be established by the Trust Administrator as follows:

          (i) If on any Rate  Determination  Date  two or more of the  Reference
     Banks provide such offered  quotations,  LIBOR for the Distribution Date in
     the succeeding month will be the arithmetic mean of such offered quotations
     (rounding  such  arithmetic  mean upwards if necessary to the nearest whole
     multiple of 1/16%).

          (ii)  If on any  Rate  Determination  Date  only  one or  none  of the
     Reference   Banks   provides  such  offered   quotations,   LIBOR  for  the
     Distribution  Date in the  succeeding  month will be whichever is higher of
     (x) LIBOR as determined on the previous Rate  Determination Date or (y) the
     Reserve  Interest  Rate.  The "Reserve  Interest Rate" will be the rate per
     annum  which  the  Trust  Administrator  determines  to be  either  (A) the
     arithmetic  mean (rounding such arithmetic mean upwards if necessary to the
     nearest whole multiple of 1/16%) of the one-month  Eurodollar lending rates
     that New York City banks selected by the Trust  Administrator  are quoting,
     on the relevant Rate Determination Date, to the principal London offices of
     at least two  leading  banks in the London  interbank  market or (B) in the
     event that the Trust  Administrator  can determine no such arithmetic mean,
     the lowest one-month  Eurodollar  lending rate that the New York City banks
     selected by the Trust  Administrator are quoting on such Rate Determination
     Date to leading European banks.

          (iii) If on any Rate  Determination  Date the Trust  Administrator  is
     required but is unable to determine the Reserve Interest Rate in the manner
     provided in the paragraph (ii) above,  LIBOR for the  Distribution  Date in
     the  succeeding  month will be LIBOR as  determined  on the  previous  Rate
     Determination  Date, or, in the case of the first Rate Determination  Date,
     5.6875%.

The   establishment  of  LIBOR  by  the  Trust   Administrator   and  the  Trust
Administrator's  subsequent  calculation of the rates of interest  applicable to
the Class A-2 and Class A-3 Certificates, in the absence of manifest error, will
be final and binding.  After a Rate Determination  Date, the Trust Administrator
shall provide the Class A Subclass Pass-Through Rates of the Class A-2 and Class
A-3  Certificates  for the related  Distribution  Date to  Beneficial  Owners or
Holders of Class A-2 and Class A-3  Certificates  who place a telephone  call to
the Trust Administrator at (704) 590-6161 and make a request therefor.

No  Certificate  shall be entitled to any benefit  under this  Agreement,  or be
valid for any purpose, unless manually countersigned by a Responsible Officer of
the  Trust  Administrator,  or  unless  there  appears  on  such  Certificate  a
certificate of  authentication  executed by the  Authenticating  Agent by manual
signature,  and such countersignature or certificate upon a Certificate shall be
conclusive evidence, and the only evidence,  that such Certificate has been duly
authenticated and delivered hereunder.  All Certificates shall be dated the date
of their authentication.

     Until such time as Definitive  Certificates  are issued pursuant to Section
5.07, each Book-Entry Certificate shall bear the following legend:

[the Clearing  Agency] to the Trust  Administrator or its agent for registration
of transfer,  exchange or payment,  and any certificate  issued is registered in
the  name  of [the  Clearing  Agency]  or such  other  name as  requested  by an
authorized  representative  of [the Clearing  Agency] and any payment is made to
[the Clearing  Agency],  any  transfer,  pledge or other use hereof for value or
otherwise by or to any person is wrongful  since the  registered  owner  hereof,
[the Clearing Agency], has an interest herein."

     (b) Upon original issuance, the Book-Entry  Certificates shall be issued in
the  form  of one or  more  typewritten  certificates,  to be  delivered  to The
Depository Trust Company,  the initial Clearing Agency, by, or on behalf of, the
Seller.  Such  Certificates  shall  initially be registered  in the  Certificate
Register  in the name of the  nominee of the  initial  Clearing  Agency,  and no
Beneficial  Owner  will  receive  a  definitive  certificate  representing  such
Beneficial Owner's interest in the Book-Entry  Certificates,  except as provided
in Section 5.07.  Unless and until  definitive,  fully  registered  certificates
("Definitive  Certificates")  have been issued to Beneficial  Owners pursuant to
Section 5.07:

          (i) the provisions of this Section  5.01(b) shall be in full force and
     effect;

          (ii) the Seller,  the Master Servicer,  the Certificate  Registrar and
     the Trust  Administrator may deal with the Clearing Agency for all purposes
     (including the making of distributions  on the Book-Entry  Certificates and
     the taking of actions by the  Holders of  Book-Entry  Certificates)  as the
     authorized representative of the Beneficial Owners;

          (iii)  to the  extent  that the  provisions  of this  Section  5.01(b)
     conflict with any other  provisions of this  Agreement,  the  provisions of
     this Section 5.01(b) shall control;

          (iv) the rights of Beneficial  Owners shall be exercised  only through
     the Clearing  Agency and shall be limited to those  established by law, the
     rules,  regulations  and  procedures of the Clearing  Agency and agreements
     between such Beneficial  Owners and the Clearing Agency and/or the Clearing
     Agency  Participants,  and all  references in this  Agreement to actions by
     Certificateholders  shall,  with  respect to the  Book-Entry  Certificates,
     refer to actions taken by the Clearing  Agency upon  instructions  from the
     Clearing  Agency  Participants,  and all  references  in this  Agreement to
     distributions, notices, reports and statements to Certificateholders shall,
     with  respect  to the  Book-Entry  Certificates,  refer  to  distributions,
     notices,  reports and statements to the Clearing Agency or its nominee,  as
     registered holder of the Book-Entry  Certificates,  as the case may be, for
     distribution to Beneficial  Owners in accordance with the procedures of the
     Clearing Agency; and

          (v) the initial  Clearing Agency will make book-entry  transfers among
     the Clearing Agency Participants and receive and transmit  distributions of
     principal  and  interest  on  the   Certificates  to  the  Clearing  Agency
     Participants,  for distribution by such Clearing Agency Participants to the
     Beneficial Owners or their nominees.

     For purposes of any  provision of this  Agreement  requiring or  permitting
actions  with the  consent of, or at the  direction  of,  Holders of  Book-Entry
Certificates  evidencing  specified Voting Interests,  such direction or consent
shall be given by  Beneficial  Owners  having the  requisite  Voting  Interests,
acting through the Clearing Agency.

     Unless and until  Definitive  Certificates  have been issued to  Beneficial
Owners pursuant to Section 5.07, copies of the reports or statements referred to
in Section 4.04 shall be available to Beneficial  Owners upon written request to
the Trust Administrator at the Corporate Trust Office.

Section 5.02.     Registration of Transfer and Exchange of
Certificates.

     (a) The Trust Administrator shall cause to be kept at one of the offices or
agencies to be maintained in  accordance  with the  provisions of Section 5.06 a
Certificate Register in which, subject to such reasonable  regulations as it may
prescribe,  the  Trust  Administrator  shall  provide  for the  registration  of
Certificates  and of transfers and exchanges of Certificates as herein provided.
The Trust Administrator shall act as, or shall appoint, a Certificate  Registrar
for the purpose of  registering  Certificates  and  transfers  and  exchanges of
Certificates as herein provided.

     Upon  surrender  for  registration  of transfer of any  Certificate  at any
office or agency  maintained  for such  purpose  pursuant  to Section  5.06 (and
subject to the  provisions of this Section 5.02) the Trust  Administrator  shall
execute,  and shall date,  authenticate  (or cause the  Authenticating  Agent to
authenticate)  and  deliver,  in  the  name  of  the  designated  transferee  or
transferees,  one or more new Certificates of a like aggregate principal portion
or Percentage Interest and of the same Class or Subclass.

     At the option of the Certificateholders,  Certificates may be exchanged for
other  Certificates of authorized  Denominations  of a like aggregate  principal
portion or Percentage  Interest and of the same Class or Subclass upon surrender
of the  Certificates to be exchanged at any such office or agency.  Whenever any
Certificates  are so surrendered  for exchange,  the Trust  Administrator  shall
execute,  and shall date,  authenticate  (or cause the  Authenticating  Agent to
authenticate) and deliver, the Certificates which the  Certificateholder  making
the exchange is entitled to receive.  Every Certificate presented or surrendered
for transfer or exchange shall (if so required by the  Certificate  Registrar or
the Trust  Administrator)  be duly endorsed by, or be  accompanied  by a written
instrument of transfer in form satisfactory to the Certificate  Registrar,  duly
executed by the Holder thereof or his attorney duly authorized in writing.

     No  service   charge  shall  be  made  for  any  transfer  or  exchange  of
Certificates,  but the Trust  Administrator  or the  Certificate  Registrar  may
require payment of a sum sufficient to cover any tax or governmental charge that
may be imposed in connection with any transfer or exchange of Certificates.

     All Certificates surrendered for transfer and exchange shall be canceled by
the Certificate  Registrar,  the Trust Administrator or the Authenticating Agent
in accordance with their standard procedures.

     (b) No transfer of a Class A-WIO,  Class A-PO Class B-3, Class B-4 or Class
B-5  Certificate  shall be made (other than the  transfer of the Class A-WIO and
Class A-PO  Certificates  to an  affiliate  of the Seller on the  Closing  Date)
unless the registration  requirements of the Securities Act of 1933, as amended,
and any applicable  State securities laws are complied with, or such transfer is
exempt from the registration  requirements under said Act and laws. In the event
that a transfer is to be made in  reliance  upon an  exemption  from said Act or
laws,  (i) unless such  transfer  is made in  reliance  on Rule 144A,  the Trust
Administrator  or the Seller  may, if such  transfer is to be made within  three
years after the later of (i) the date of the  initial  sale of  Certificates  or
(ii) the last date on which the Seller or any affiliate  thereof was a Holder of
the Certificates proposed to be transferred,  require a Class A-WIO, Class A-PO,
Class B-3, Class B-4 or Class B-5 Certificateholder to deliver a written Opinion
of Counsel  acceptable  to and in form and substance  satisfactory  to the Trust
Administrator  and the  Seller,  to the effect  that such  transfer  may be made
pursuant to an  exemption,  describing  the  applicable  exemption and the basis
therefor, from said Act and laws or is being made pursuant to said Act and laws,
which Opinion of Counsel shall not be an expense of the Trust Administrator, the
Trustee,  the Seller or the Master  Servicer,  and (ii) the Trust  Administrator
shall  require the  transferee  to execute an  investment  letter in the form of
Exhibit J hereto certifying to the Seller and the Trust  Administrator the facts
surrounding such transfer,  which  investment  letter shall not be an expense of
the Trust  Administrator,  the Trustee,  the Seller or the Master Servicer.  The
Holder  of a Class  A-WIO,  Class  A-PO,  Class  B-3,  Class  B-4 or  Class  B-5
Certificate  desiring to effect such transfer  shall,  and does hereby agree to,
indemnify the Trust Administrator,  the Trustee, the Seller, the Master Servicer
and any Paying Agent acting on behalf of the Trustee  against any liability that
may result if the  transfer is not so exempt or is not made in  accordance  with
such federal and state laws.  Neither the Seller nor the Trust  Administrator is
under an obligation to register the Class A-WIO,  Class A-PO,  Class B-3,  Class
B-4 or Class B-5 Certificates under said Act or any other securities law.

     (c)  No  transfer  of a  Class  A-WIO,  Class  A-PO,  Class  M or  Class  B
Certificate  shall be made (other than the transfer of the Class A-WIO and Class
A-PO  Certificates to an affiliate of the Seller on the Closing Date) unless the
Trust  Administrator  shall have received (i) a  representation  letter from the
transferee in the form of Exhibit J hereto, in the case of a Class A-WIO,  Class
A-PO, Class B-3, Class B-4 or Class B-5 Certificate, or in the form of Exhibit K
hereto,  in the case of a Class M,  Class B-1 or Class B-2  Certificate,  to the
effect that either (a) such transferee is not an employee  benefit plan or other
retirement  arrangement  subject to Title I of ERISA or Code Section  4975, or a
governmental plan, as defined in Section 3(32) of ERISA, subject to any federal,
state or local law ("Similar  Law") which is to a material extent similar to the
foregoing provisions of ERISA or the Code (collectively,  a "Plan") and is not a
person  acting  on  behalf  of or  using  the  assets  of any such  Plan,  which
representation  letter shall not be an expense of the Trust  Administrator,  the
Trustee,  the Seller or the Master Servicer or (b) (other than with respect to a
Class  A-WIO or Class  A-PO  Certificate)  if such  transferee  is an  insurance
company, the source of funds used to purchase the Class M or Class B Certificate
is an "insurance  company  general  account" (as such term is defined in Section
V(e) of Prohibited Transaction Class Exemption 95-60 ("PTE 95-60"), 60 Fed. Reg.
35925 (July 12,  1995)) and there is no Plan with respect to which the amount of
such general  account's  reserves and liabilities for the contract(s) held by or
on behalf of such Plan and all other Plans  maintained  by the same employer (or
affiliate  thereof as  defined  in Section  V(a)(1) of PTE 95-60) or by the same
employee  organization  exceeds 10% of the total of all reserves and liabilities
of such general  account (as such amounts are  determined  under Section I(a) of
PTE  95-60)  at the date of  acquisition  or (ii) in the case of any such  Class
A-WIO, Class A-PO, Class M or Class B Certificate  presented for registration in
the name of a Plan,  or a trustee  of any such  Plan,  (A) an Opinion of Counsel
satisfactory  to the Trust  Administrator  and the Seller to the effect that the
purchase  or  holding  of such  Class  A-WIO,  Class  A-PO,  Class M or  Class B
Certificate will not result in the assets of the Trust Estate being deemed to be
"plan assets" and subject to the prohibited transaction provisions of ERISA, the
Code or Similar Law and will not subject the Trust  Administrator,  the Trustee,
the  Seller or the  Master  Servicer  to any  obligation  in  addition  to those
undertaken in this  Agreement,  which Opinion of Counsel shall not be an expense
of the Trust  Administrator,  the Trustee, the Seller or the Master Servicer and
(B) such other opinions of counsel, officer's certificates and agreements as the
Seller or the Master  Servicer  may require in  connection  with such  transfer,
which opinions of counsel, officers' certificates and agreements shall not be an
expense  of the Trust  Administrator,  the  Trustee,  the  Seller or the  Master
Servicer.  The Class A-WIO,  Class A-PO, Class M and Class B Certificates  shall
bear a  legend  referring  to  the  foregoing  restrictions  contained  in  this
paragraph.

     (d) No legal or beneficial  interest in all or any portion of the Class A-R
or Class  A-LR  Certificate  may be  transferred  directly  or  indirectly  to a
"disqualified  organization" within the meaning of Code Section 860E(e)(5) or an
agent  of  a  disqualified   organization   (including  a  broker,  nominee,  or
middleman),  to a Plan or a Person  investing the assets of a Plan (such plan or
Person,  an  "ERISA  Prohibited  Holder")  or  to  an  individual,  corporation,
partnership or other person unless such transferee (i) is not a Non-U.S.  Person
or (ii) is a Non-U.S.  Person that holds the Class A-R or Class A-LR Certificate
in connection  with the conduct of a trade or business  within the United States
and has furnished the transferor and the Trust  Administrator  with an effective
Internal  Revenue  Service  Form  4224 or (iii) is a  Non-U.S.  Person  that has
delivered to both the  transferor  and the Trust  Administrator  an opinion of a
nationally  recognized  tax counsel to the effect that the transfer of the Class
A-R or Class A-LR  Certificate to it is in accordance  with the  requirements of
the Code and the  regulations  promulgated  thereunder and that such transfer of
the Class A-R or Class A-LR  Certificate  will not be  disregarded  for  federal
income tax purposes  (any such person who is not covered by clauses (i), (ii) or
(iii) above being referred to herein as a "Non-permitted  Foreign Holder"),  and
any  such  purported  transfer  shall  be void and  have no  effect.  The  Trust
Administrator  shall  not  execute,  and shall  not  authenticate  (or cause the
Authenticating Agent to authenticate) and deliver, a new Class A-R or Class A-LR
Certificate in connection with any such transfer to a disqualified  organization
or agent thereof (including a broker, nominee or middleman), an ERISA Prohibited
Holder or a Non-permitted  Foreign Holder, and neither the Certificate Registrar
nor  the  Trust   Administrator   shall  accept  a  surrender  for  transfer  or
registration  of  transfer,  or register the transfer of, the Class A-R or Class
A-LR  Certificate,  unless  the  transferor  shall  have  provided  to the Trust
Administrator  an  affidavit,  substantially  in the form  attached as Exhibit H
hereto, signed by the transferee,  to the effect that the transferee is not such
a  disqualified  organization,   an  agent  (including  a  broker,  nominee,  or
middleman)  for any  entity  as to  which  the  transferee  has not  received  a
substantially  similar affidavit,  an ERISA Prohibited Holder or a Non-permitted
Foreign  Holder,  which affidavit shall contain the consent of the transferee to
any such  amendments of this Agreement as may be required to further  effectuate
the  foregoing  restrictions  on  transfer  of  the  Class  A-R  or  Class  A-LR
Certificate  to  disqualified   organizations,   ERISA  Prohibited   Holders  or
Non-permitted  Foreign Holders.  Such affidavit shall also contain the statement
of the transferee  that (i) the transferee  has  historically  paid its debts as
they have  come due and  intends  to do so in the  future,  (ii) the  transferee
understands  that it may incur  liabilities in excess of cash flows generated by
the residual interest, (iii) the transferee intends to pay taxes associated with
holding the residual  interest as they become due and (iv) the  transferee  will
not transfer the Class A-R or Class A-LR  Certificate to any Person who does not
provide an affidavit substantially in the form attached as Exhibit H hereto.

     The  affidavit  described in the  preceding  paragraph,  if not executed in
connection with the initial issuance of the Class A-R or Class A-LR Certificate,
shall be  accompanied  by a written  statement in the form attached as Exhibit I
hereto,  signed  by the  transferor,  to the  effect  that as of the time of the
transfer,  the  transferor  has no actual  knowledge  that the  transferee  is a
disqualified  organization,  ERISA Prohibited  Holder or  Non-permitted  Foreign
Holder,  and has no knowledge or reason to know that the statements  made by the
transferee  with  respect to clauses  (i) and (iii) of the last  sentence of the
preceding  paragraph  are not true.  The Class A-R and Class  A-LR  Certificates
shall bear a legend  referring to the foregoing  restrictions  contained in this
paragraph and the preceding paragraph.

     Upon notice to the Master Servicer that any legal or beneficial interest in
any  portion of the Class A-R or Class A-LR  Certificate  has been  transferred,
directly  or  indirectly,  to  a  disqualified  organization  or  agent  thereof
(including a broker,  nominee,  or middleman) in  contravention of the foregoing
restrictions, (i) such transferee shall be deemed to hold the Class A-R or Class
A-LR  Certificate in  constructive  trust for the last  transferor who was not a
disqualified  organization  or  agent  thereof,  and  such  transferor  shall be
restored as the owner of such Class A-R or Class A-LR  Certificate as completely
as if such transfer had never  occurred,  provided that the Master Servicer may,
but is not required to, recover any  distributions  made to such transferee with
respect to Class A-R or Class  A-LR  Certificate,  and (ii) the Master  Servicer
agrees to furnish to the Internal  Revenue  Service and to any transferor of the
Class A-R or Class A-LR Certificate or such agent (within 60 days of the request
therefor  by  the  transferor  or  agent)  such  information  necessary  to  the
application  of Code Section  860E(e) as may be required by the Code,  including
but not limited to the present value of the total anticipated  excess inclusions
with respect to the Class A-R or Class A-LR Certificate (or portion thereof) for
periods after such transfer. At the election of the Master Servicer, the cost to
the Master Servicer of computing and furnishing such  information may be charged
to the transferor or such agent referred to above;  however, the Master Servicer
shall in no event be excused from furnishing such information.

Section 5.03.     Mutilated, Destroyed, Lost or Stolen Certificates.

     If (i) any mutilated  Certificate is surrendered to the Trust Administrator
or the  Authenticating  Agent, or the Trust  Administrator or the Authenticating
Agent receives evidence to its satisfaction of the destruction, loss or theft of
any Certificate,  and (ii) there is delivered to the Trust  Administrator or the
Authenticating  Agent such  security or  indemnity as may be required by them to
hold  each of them  harmless,  then,  in the  absence  of  notice  to the  Trust
Administrator  or the  Authenticating  Agent  that  such  Certificate  has  been
acquired by a bona fide  purchaser,  the Trust  Administrator  shall execute and
authenticate (or cause the Authenticating Agent to authenticate) and deliver, in
exchange  for or in lieu  of any  such  mutilated,  destroyed,  lost  or  stolen
Certificate, a new Certificate of like tenor and principal portion or Percentage
Interest  and of the  same  Class or  Subclass.  Upon  the  issuance  of any new
Certificate  under this  Section,  the Trust  Administrator  or the  Certificate
Registrar may require the payment of a sum  sufficient to cover any tax or other
governmental  charge  that may be  imposed  in  relation  thereto  and any other
expense  (including  the fees and  expenses  of the Trust  Administrator  or the
Authenticating Agent) in connection therewith.  Any duplicate Certificate issued
pursuant to this Section shall constitute complete and indefeasible  evidence of
ownership in the Trust Estate, as if originally issued, whether or not the lost,
stolen, or destroyed Certificate shall be found at any time.

Section 5.04.     Persons Deemed Owners.

     Prior  to  the  due  presentation  of a  Certificate  for  registration  of
transfer, the Seller, the Master Servicer, the Trustee, the Trust Administrator,
the Certificate Registrar and any agent of the Seller, the Master Servicer,  the
Trustee,  the Trust  Administrator  or the  Certificate  Registrar may treat the
Person  in  whose  name  any  Certificate  is  registered  as the  owner of such
Certificate for the purpose of receiving distributions pursuant to Section 4.01,
and for all other  purposes  whatsoever,  and  neither  the  Seller,  the Master
Servicer,  the Trustee, the Trust Administrator,  the Certificate  Registrar nor
any  agent  of  the  Seller,  the  Master  Servicer,   the  Trustee,  the  Trust
Administrator,  or the Certificate  Registrar shall be affected by notice to the
contrary.

Section 5.05.     Access to List of Certificateholders' Names and
Addresses.

     (a) If the Trust Administrator is not acting as Certificate Registrar,  the
Certificate  Registrar  shall  furnish  or cause to be  furnished  to the  Trust
Administrator,  within 15 days after receipt by the  Certificate  Registrar of a
request by the Trust Administrator in writing, a list, in such form as the Trust
Administrator  may  reasonably  require,  of  the  names  and  addresses  of the
Certificateholders of each Class or Subclass as of the most recent Record Date.

     (b)  If  five  or  more  Certificateholders  (hereinafter  referred  to  as
"applicants") apply in writing to the Trust Administrator,  and such application
states that the applicants  desire to communicate with other  Certificateholders
with respect to their rights under this Agreement or under the  Certificates and
is accompanied by a copy of the communication  which such applicants  propose to
transmit,  then  the  Trust  Administrator  shall,  within  five  Business  Days
following the receipt of such application,  afford such applicants access during
normal business hours to the most recent list of Certificateholders  held by the
Trust Administrator. If such a list is as of the date more than 90 days prior to
the date of receipt of such applicants'  request and the Trust  Administrator is
not the Certificate  Registrar,  the Trust  Administrator shall promptly request
from the  Certificate  Registrar a current  list as provided  in  paragraph  (a)
hereof,  and shall  afford such  applicants  access to such list  promptly  upon
receipt.

     (c) Every Certificateholder, by receiving and holding a Certificate, agrees
with the Seller,  the Master  Servicer,  the  Certificate  Registrar,  the Trust
Administrator and the Trustee that neither the Seller, the Master Servicer,  the
Certificate  Registrar,  the Trust  Administrator  nor the Trustee shall be held
accountable by reason of the disclosure of any such information as to the names,
addresses  and  Percentage  Interests  of  the   Certificateholders   hereunder,
regardless of the source from which such information was delivered.

Section 5.06.     Maintenance of Office or Agency.

     The Trust Administrator will maintain,  at its expense, an office or agency
where  Certificates  may be surrendered for registration of transfer or exchange
and where notices and demands to or upon the Certificate Registrar in respect of
the  Certificates  and this  Agreement  may be served.  The Trust  Administrator
initially  designates  the Corporate  Trust Office and the  principal  corporate
trust office of the  Authenticating  Agent,  if any, as its offices and agencies
for said purposes.

Section 5.07.     Definitive Certificates.

     If (i)(A) the Master Servicer  advises the Trust  Administrator  in writing
that the Clearing  Agency is no longer willing or able properly to discharge its
responsibilities as depository with respect to the Book-Entry Certificates,  and
(B) the Master  Servicer  is unable to locate a  qualified  successor,  (ii) the
Master Servicer, at its option,  advises the Trust Administrator in writing that
it elects to terminate  the  book-entry  system  through the Clearing  Agency or
(iii) after the occurrence of dismissal or  resignation of the Master  Servicer,
Beneficial Owners  representing  aggregate Voting Interests of not less than 51%
of the aggregate  Voting  Interests of each  outstanding  Subclass of Book-Entry
Certificates  advise the Trust  Administrator  through the  Clearing  Agency and
Clearing Agency  Participants  in writing that the  continuation of a book-entry
system  through the  Clearing  Agency is no longer in the best  interests of the
Beneficial Owners, the Trust  Administrator  shall notify the Beneficial Owners,
through the  Clearing  Agency,  of the  occurrence  of any such event and of the
availability  of Definitive  Certificates  to Beneficial  Owners  requesting the
same.  Upon surrender to the Trust  Administrator  by the Clearing Agency of the
Certificates  held of  record  by its  nominee,  accompanied  by  reregistration
instructions and directions to execute and  authenticate  new Certificates  from
the Master  Servicer,  the Trust  Administrator  shall execute and  authenticate
Definitive  Certificates for delivery at its Corporate Trust Office.  The Master
Servicer  shall  arrange  for,  and will  bear all costs of,  the  printing  and
issuance  of such  Definitive  Certificates.  Neither  the  Seller,  the  Master
Servicer,  the Trustee nor the Trust Administrator shall be liable for any delay
in delivery of such  instructions  by the Clearing  Agency and may  conclusively
rely on, and shall be protected in relying on, such instructions.

Section 5.08.     Notices to Clearing Agency.

     Whenever  notice  or  other  communication  to the  Holders  of  Book-Entry
Certificates  is  required  under this  Agreement,  unless and until  Definitive
Certificates  shall have been issued to  Beneficial  Owners  pursuant to Section
5.07,  the Trust  Administrator  shall give all such notices and  communications
specified  herein  to be given to  Holders  of  Book-Entry  Certificates  to the
Clearing Agency.

THE SELLER AND THE MASTER SERVICER

Section 6.01.     Liability of the Seller and the Master Servicer.

     The  Seller  and the Master  Servicer  shall  each be liable in  accordance
herewith  only to the  extent of the  obligations  specifically  imposed by this
Agreement and undertaken hereunder by the Seller and the Master Servicer.

Section 6.02.     Merger or Consolidation of the Seller or the Master
Servicer.

     Subject to the following paragraph, the Seller and the Master Servicer each
will keep in full effect its  existence,  rights and franchises as a corporation
under the laws of the  jurisdiction  of its  incorporation,  and will obtain and
preserve  its  qualification  to do  business as a foreign  corporation  in each
jurisdiction in which such qualification is or shall be necessary to protect the
validity and  enforceability  of this Agreement,  the Certificates or any of the
Mortgage Loans and to perform its respective duties under this Agreement.

     The Seller or the Master  Servicer  may be merged or  consolidated  with or
into any  Person,  or  transfer  all or  substantially  all of its assets to any
Person,  in which case any Person  resulting from any merger or consolidation to
which the Seller or Master Servicer shall be a party,  or any Person  succeeding
to the business of the Seller or Master Servicer,  shall be the successor of the
Seller or Master  Servicer  hereunder,  without the  execution  or filing of any
paper or any  further  act on the part of any of the  parties  hereto,  anything
herein to the contrary notwithstanding;  provided, however, that, in the case of
the Master  Servicer,  any such successor or resulting Person shall be qualified
to service mortgage loans for FNMA or FHLMC.

Section 6.03.     Limitation on Liability of the Seller, the Master
Servicer and Others.

     Neither the Seller nor the Master Servicer nor any subcontractor nor any of
the partners,  directors,  officers, employees or agents of any of them shall be
under any liability to the Trust Estate or the  Certificateholders  and all such
Persons shall be held harmless for any action taken or for  refraining  from the
taking of any action in good faith pursuant to this Agreement,  or for errors in
judgment;  provided,  however,  that this  provision  shall not protect any such
Person  against  any breach of  warranties  or  representations  made  herein or
against  any  liability  which would  otherwise  be imposed by reason of willful
misfeasance,  bad faith or gross  negligence in the  performance of duties or by
reason of reckless  disregard of obligations and duties  hereunder.  The Seller,
the Master Servicer,  any  subcontractor,  and any partner,  director,  officer,
employee  or agent of any of them shall be entitled  to  indemnification  by the
Trust Estate and will be held  harmless  against any loss,  liability or expense
incurred in connection  with any legal action  relating to this Agreement or the
Certificates,  other than any loss,  liability or expense  incurred by reason of
willful misfeasance,  bad faith or gross negligence in the performance of his or
its  duties  hereunder  or by  reason  of  reckless  disregard  of  his  or  its
obligations and duties hereunder. The Seller, the Master Servicer and any of the
directors, officers, employees or agents of either may rely in good faith on any
document of any kind which,  prima facie, is properly  executed and submitted by
any Person respecting any matters arising hereunder.  Neither the Seller nor the
Master Servicer shall be under any obligation to appear in,  prosecute or defend
any legal action  unless such action is related to its  respective  duties under
this  Agreement  and which in its opinion  does not involve it in any expense or
liability;  provided, however, that the Seller or the Master Servicer may in its
discretion  undertake  any such action which it may deem  necessary or desirable
with respect to this  Agreement and the rights and duties of the parties  hereto
and the interests of the Certificateholders  hereunder if the Certificateholders
offer to the  Seller  or the  Master  Servicer,  as the case may be,  reasonable
security or indemnity  against the costs,  expenses and liabilities which may be
incurred therein or thereby. In such event, the legal expenses and costs of such
action  and any  liability  resulting  therefrom  shall be  expenses,  costs and
liabilities of the Trust Estate,  and the Seller or the Master Servicer shall be
entitled to be  reimbursed  therefor out of the  Certificate  Account,  and such
amounts shall,  on the following  Distribution  Date or  Distribution  Dates, be
allocated  in  reduction  of  distributions  on the Class A, Class M and Class B
Certificates  in the same manner as Realized  Losses are  allocated  pursuant to
Section 4.02(a).

Section 6.04.     Resignation of the Master Servicer.

     The Master Servicer shall not resign from the obligations and duties hereby
imposed on it except upon  determination that its duties hereunder are no longer
permissible  under  applicable  law or are in  material  conflict  by  reason of
applicable  law  with  any  other   activities   carried  on  by  it.  Any  such
determination  permitting  the  resignation  of the  Master  Servicer  shall  be
evidenced  by an Opinion of Counsel to such effect  delivered to the Trustee and
the Trust  Administrator.  No such resignation  shall become effective until the
Trustee,  the Trust Administrator or a successor servicer shall have assumed the
Master  Servicer's   responsibilities,   duties,   liabilities  and  obligations
hereunder.

Section 6.05.     Compensation to the Master Servicer.

     The Master Servicer shall be entitled to receive a monthly fee equal to the
Master  Servicing  Fee,  as  compensation  for  services  rendered by the Master
Servicer under this Agreement.  The Master Servicer also will be entitled to any
late reporting fees paid by a Servicer  pursuant to its Servicing  Agreement and
any  investment  income  on funds  on  deposit  in the  Certificate  Account  as
additional compensation.

Section 6.06.     Assignment or Delegation of Duties by Master
Servicer.

     The  Master  Servicer  shall not  assign  or  transfer  any of its  rights,
benefits or privileges under this Agreement to any other Person,  or delegate to
or subcontract  with, or authorize or appoint any other Person to perform any of
the duties,  covenants or  obligations  to be  performed by the Master  Servicer
without the prior  written  consent of the Trustee and the Trust  Administrator,
and any agreement,  instrument or act purporting to effect any such  assignment,
transfer,   delegation  or  appointment  shall  be  void.   Notwithstanding  the
foregoing,  the Master  Servicer  shall have the right without the prior written
consent of the Trustee or the Trust  Administrator  (i) to assign its rights and
delegate its duties and obligations hereunder;  provided,  however, that (a) the
purchaser or transferee  accepting such assignment or delegation is qualified to
service mortgage loans for FNMA or FHLMC, is satisfactory to the Trustee and the
Trust Administrator,  in the exercise of its reasonable  judgment,  and executes
and delivers to the Trustee and the Trust  Administrator  an agreement,  in form
and   substance   reasonably   satisfactory   to  the   Trustee  and  the  Trust
Administrator,  which  contains an assumption by such purchaser or transferee of
the due and punctual  performance  and observance of each covenant and condition
to be performed or observed by the Master Servicer  hereunder from and after the
date of such agreement;  and (b) each  applicable  Rating Agency's rating of any
Certificates in effect immediately prior to such assignment, sale or transfer is
not  reasonably  likely to be qualified,  downgraded or withdrawn as a result of
such assignment, sale or transfer and the Certificates are not reasonably likely
to be placed on credit  review  status by any such  Rating  Agency;  and (ii) to
delegate to, subcontract with, authorize,  or appoint an affiliate of the Master
Servicer to perform and carry out any duties,  covenants  or  obligations  to be
performed and carried out by the Master Servicer under this Agreement and hereby
agrees so to delegate, subcontract,  authorize or appoint to an affiliate of the
Master Servicer any duties, covenants or obligations to be performed and carried
out by the  Master  Servicer  to the  extent  that  such  duties,  covenants  or
obligations  are to be  performed  in any state or  states  in which the  Master
Servicer is not authorized to do business as a foreign  corporation but in which
the  affiliate  is so  authorized.  In no case,  however,  shall  any  permitted
assignment  and delegation  relieve the Master  Servicer of any liability to the
Trustee, the Trust Administrator or the Seller under this Agreement, incurred by
it prior to the time that the conditions contained in clause (i) above are met.

Section 6.07.     Indemnification of Trustee, Trust Administrator and
Seller by Master Servicer.

     The Master  Servicer  shall  indemnify and hold  harmless the Trustee,  the
Trust  Administrator  and the Seller and any director,  officer or agent thereof
against any loss, liability or expense,  including  reasonable  attorney's fees,
arising out of, in connection with or incurred by reason of willful misfeasance,
bad faith or  negligence  in the  performance  of duties of the Master  Servicer
under this Agreement or by reason of reckless  disregard of its  obligations and
duties under this  Agreement.  Any payment  pursuant to this Section made by the
Master Servicer to the Trustee,  the Trust  Administrator or the Seller shall be
from such entity's own funds, without reimbursement  therefor. The provisions of
this Section 6.07 shall survive the termination of this Agreement.

     shall have remained in force  undischarged  and unstayed for a period of 60
     days; or

          (iv)  the  Master  Servicer  shall  consent  to the  appointment  of a

     liabilities, voluntary liquidation or similar proceedings of or relating to
     the Master Servicer,  or of or relating to all or substantially  all of its
     property; or

          (v) the Master  Servicer  shall admit in writing its  inability to pay
     its debts  generally as they become due, file a petition to take  advantage
     of any applicable insolvency, bankruptcy or reorganization statute, make an
     assignment for the benefit of its creditors or voluntarily  suspend payment

     it,  such  that the  resulting  entity  does not  meet the  criteria  for a
     successor servicer, as specified in Section 6.02 hereof; or

          (vii) the Master Servicer and any subservicer  appointed by it becomes
     ineligible  to  service  for  both  FNMA  and  FHMLC,  which  ineligibility
     continues unremedied for a period of 90 days.

then, and in each and every such case,  subject to applicable law, so long as an
Event of Default shall not have been remedied, either the Trustee or the holders
of  Certificates  evidencing  in the  aggregate  not  less  than  66 2/3% of the
aggregate Voting Interest represented by all Certificates,  by notice in writing
to the Master Servicer and the Trust  Administrator (and to the Trustee if given
by the  Certificateholders)  may terminate all of the rights and  obligations of
the Master Servicer under this Agreement and in and to the Mortgage  Loans,  but
without  prejudice  to any  rights  which the  Master  Servicer  may have to the
aggregate  Master Servicing Fees due prior to the date of transfer of the Master
Servicer's responsibilities  hereunder,  reimbursement of expenses to the extent
permitted by this  Agreement,  Periodic  Advances and other  advances of its own
funds. Upon receipt by the Master Servicer of such written notice, all authority
and power of the Master Servicer under this  Agreement,  whether with respect to
the Certificates or the Mortgage Loans or otherwise, shall pass to and be vested
in the Trust  Administrator  on behalf of the Trustee pursuant to and under this
Section, subject to the provisions of Section 7.05; and, without limitation, the
Trust  Administrator on behalf of the Trustee is hereby authorized and empowered
to execute and deliver, on behalf of the Master Servicer, as attorney-in-fact or
otherwise, any and all documents and other instruments,  and to do or accomplish
all other acts or things necessary or appropriate to effect the purposes of such
notice of  termination,  whether to complete  the transfer  and  endorsement  or
assignment of the Mortgage Loans and related documents or otherwise.  The Master
Servicer  agrees to cooperate  with the Trust  Administrator  and the Trustee in
effecting the termination of the Master Servicer's  responsibilities  and rights
hereunder  and shall  promptly  provide the Trustee  all  documents  and records
reasonably  requested  by it  to  enable  it to  assume  the  Master  Servicer's
functions  hereunder and shall promptly also transfer to the Trust Administrator
on behalf of the Trustee  all  amounts  which then have been or should have been
deposited  in the  Certificate  Account  by the  Master  Servicer  or which  are
thereafter received by the Master Servicer with respect to the Mortgage Loans.

Section 7.02.     Other Remedies of Trustee.

     During the  continuance  of any Event of Default,  so long as such Event of
Default  shall not have been  remedied,  the Trustee,  in addition to the rights
specified in Section 7.01,  shall have the right,  in its own name as trustee of
an express  trust,  to take all  actions  now or  hereafter  existing at law, in
equity or by statute to enforce  its  rights  and  remedies  and to protect  the
interests,  and  enforce  the rights  and  remedies,  of the  Certificateholders
(including the institution and prosecution of all judicial,  administrative  and
other  proceedings  and the  filing of  proofs  of claim and debt in  connection
therewith).  Except as otherwise expressly provided in this Agreement, no remedy
provided for by this Agreement shall be exclusive of any other remedy,  and each
and every remedy shall be cumulative  and in addition to any other remedy and no
delay or omission to exercise any right or remedy shall impair any such right or
remedy or shall be deemed to be a waiver of any Event of Default.

Section 7.03.     Directions by Certificateholders and
Duties of Trustee During Event of Default.

     During the  continuance  of any Event of Default,  Holders of  Certificates
evidencing in the aggregate not less than 25% of the aggregate  Voting  Interest
represented  by all  Certificates  may  direct  the  time,  method  and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred upon the Trustee,  under this Agreement;  provided,
however,  that the  Trustee  shall be under no  obligation  to  pursue  any such
remedy,  or to  exercise  any of the  trusts  or  powers  vested  in it by  this
agreement (including, without limitation, (i) the conducting or defending of any
administrative action or litigation hereunder or in relation hereto and (ii) the
terminating  of the Master  Servicer  from its  rights  and  duties as  servicer
hereunder) at the request, order or direction of any of the  Certificateholders,
unless such  Certificateholders  shall have  offered to the  Trustee  reasonable
security or indemnity  against the cost,  expenses and liabilities  which may be
incurred  therein  or  thereby  and,  provided  further,  that,  subject  to the
provisions  of  Section  8.01,  the  Trustee  shall have the right to decline to
follow any such  direction  if the  Trustee,  in  accordance  with an Opinion of
Counsel,  determines  that the action or proceeding so directed may not lawfully
be  taken  or if the  Trustee  in good  faith  determines  that  the  action  or
proceeding  so directed  would  involve it in personal  liability or be unjustly
prejudicial to the nonassenting Certificateholders.

Section 7.04.     Action upon Certain Failures of the
Master Servicer and upon Event of Default.

     In the  event  that the  Trustee  or the  Trust  Administrator  shall  have
knowledge of any failure of the Master Servicer  specified in Section 7.01(i) or
(ii) which would become an Event of Default upon the Master  Servicer's  failure
to remedy the same after  notice,  the Trustee or Trust  Administrator  may, but
need not if the Trustee or Trust Administrator, as the case may be, deems it not
in the  Certificateholders'  best  interest,  give notice  thereof to the Master
Servicer. For all purposes of this Agreement, in the absence of actual knowledge
by a  corporate  trust  officer of the Trustee or the Trust  Administrator,  the
Trustee or the Trust  Administrator,  as the case may be, shall not be deemed to
have  knowledge  of any failure of the Master  Servicer as  specified in Section
7.01(i) and (ii) or any Event of Default unless  notified  thereof in writing by
the Master Servicer or by a Certificateholder.

Section 7.05.     Trust Administrator to Act; Appointment of
Successor.

     When the Master Servicer receives notice of termination pursuant to Section
7.01 or the Trustee or the Trust  Administrator  receives the resignation of the
Master Servicer evidenced by an Opinion of Counsel pursuant to Section 6.04, the
Trust  Administrator  on behalf of the  Trustee  shall be the  successor  in all
respects to the Master  Servicer in its capacity as master  servicer  under this
Agreement and the  transactions  set forth or provided for herein and shall have
the rights and  powers  and be subject to all the  responsibilities,  duties and
liabilities  relating  thereto  placed on the Master  Servicer  by the terms and
provisions  hereof and in its  capacity  as such  successor  shall have the same
limitation of liability herein granted to the Master Servicer. In the event that
the Trust  Administrator  is  succeeding  to the Master  Servicer  as the Master
Servicer, as compensation therefor, the Trust Administrator shall be entitled to
receive  monthly such portion of the Master  Servicing  Fee,  together with such
other  servicing  compensation  as is  agreed  to at  such  time  by  the  Trust
Administrator  and the Master  Servicer,  but in no event more than 25%  thereof
until the date of final cessation of the Master Servicer's  servicing activities
hereunder.  Notwithstanding  the above, the Trust Administrator may, if it shall
be  unwilling  to so act,  or  shall,  if it is  unable to so act or to obtain a
qualifying  bid as described  below,  appoint,  or petition a court of competent
jurisdiction  to  appoint,  any housing and home  finance  institution,  bank or
mortgage  servicing  institution having a net worth of not less than $10,000,000
and  meeting  such other  standards  for a  successor  servicer as are set forth
herein,  as the successor to the Master Servicer  hereunder in the assumption of
all or any part of the  responsibilities,  duties or  liabilities  of the Master
Servicer  hereunder;  provided,  however,  that  until such a  successor  master
servicer  is  appointed  and  has  assumed  the  responsibilities,   duties  and
liabilities of the Master  Servicer  hereunder,  the Trust  Administrator  shall
continue  as the  successor  to the  Master  Servicer  as  provided  above.  The
compensation of any successor  master servicer so appointed shall not exceed the
compensation   specified  in  Section  6.05  hereof.  In  the  event  the  Trust
Administrator  is  required  to  solicit  bids  as  provided  above,  the  Trust
Administrator shall solicit, by public announcement,  bids from housing and home
finance  institutions,  banks and mortgage  servicing  institutions  meeting the
qualifications  set forth in the  preceding  sentence  for the  purchase  of the
master  servicing  functions.  Such public  announcement  shall specify that the
successor  master  servicer  shall be  entitled to the full amount of the Master
Servicing Fee as compensation together with the other servicing  compensation in
the form of late reporting fees or otherwise as provided in Section 6.05. Within
30 days  after  any such  public  announcement,  the Trust  Administrator  shall
negotiate and effect the sale,  transfer and assignment of the master  servicing
rights and  responsibilities  hereunder to the qualified  party  submitting  the
highest  qualifying  bid.  The Trust  Administrator  shall  deduct all costs and
expenses of any public  announcement and of any sale, transfer and assignment of
the servicing rights and responsibilities hereunder from any sum received by the
Trust Administrator from the successor to the Master Servicer in respect of such
sale, transfer and assignment.  After such deductions, the remainder of such sum
shall be paid by the Trust  Administrator  to the Master Servicer at the time of
such sale, transfer and assignment to the Master Servicer's successor. The Trust
Administrator  and such successor  shall take such action,  consistent with this
Agreement,  as shall be necessary to effectuate any such succession.  The Master
Servicer  agrees to cooperate  with the Trust  Administrator  and any  successor
servicer  in  effecting  the  termination  of the  Master  Servicer's  servicing
responsibilities  and rights  hereunder  and shall  promptly  provide  the Trust
Administrator or such successor master  servicer,  as applicable,  all documents
and  records  reasonably  requested  by it to  enable it to  assume  the  Master
Servicer's  function  hereunder  and shall  promptly  also transfer to the Trust
Administrator  or such successor  master  servicer,  as applicable,  all amounts
which then have been or should have been deposited in the Certificate Account by
the Master Servicer or which are thereafter received by the Master Servicer with
respect to the Mortgage  Loans.  Neither the Trust  Administrator  nor any other
successor  master servicer shall be deemed to be in default  hereunder by reason
of any failure to make, or any delay in making,  any  distribution  hereunder or
any portion thereof caused by (i) the failure of the Master Servicer to deliver,
or  any  delay  in  delivering,  cash,  documents  or  records  to it,  or  (ii)
restrictions  imposed by any regulatory  authority having  jurisdiction over the
Master Servicer.  Notwithstanding  anything to the contrary contained in Section
7.01 above or this Section  7.05,  the Master  Servicer  shall retain all of its
rights and  responsibilities  hereunder,  and no successor  (including the Trust
Administrator)  shall  succeed  thereto,  if  the  assumption  thereof  by  such
successor  would cause the rating  assigned to any  Certificates  to be revoked,
downgraded or placed on credit review status (other than for possible upgrading)
by either Rating Agency and the retention  thereof by the Master  Servicer would
avert such revocation, downgrading or review.

Section 7.06.     Notification to Certificateholders.

     Upon any  termination of the Master  Servicer or appointment of a successor
master servicer,  in each case as provided herein, the Trust Administrator shall
give prompt  written notice thereof to  Certificateholders  at their  respective
addresses appearing in the Certificate  Register.  The Trust Administrator shall
also,  within 45 days after the  occurrence of any Event of Default known to the
Trust Administrator,  give written notice thereof to Certificateholders at their
respective addresses appearing in the Certificate Register, unless such Event of
Default shall have been cured or waived within said 45 day period.

ARTICLE VIII

CONCERNING THE TRUSTEE AND THE TRUST ADMINISTRATOR

Section 8.01.     Duties of Trustee and Trust Administrator.

     The  Trustee and the Trust  Administrator,  prior to the  occurrence  of an
Event of Default  and after the  curing of all Events of Default  which may have
occurred,  undertakes  to  perform  such  duties  and only  such  duties  as are
specifically  set  forth in this  Agreement.  In case an Event  of  Default  has
occurred  (which has not been cured),  the Trustee and the Trust  Administrator,
subject to the provisions of Sections 7.01,  7.03, 7.04 and 7.05, shall exercise
such of the rights and powers vested in it by this  Agreement,  and use the same
degree of care and skill in its exercise as a prudent investor would exercise or
use under the circumstances in the conduct of such investor's own affairs.

     The Trustee and the Trust  Administrator,  upon receipt of all resolutions,
certificates,   statements,   opinions,  reports,  documents,  orders  or  other
instruments  furnished  to the  Trustee and the Trust  Administrator,  which are
specifically  required  to be  furnished  pursuant  to  any  provision  of  this
Agreement, shall examine them to determine whether they are in the form required
by  this  Agreement;   provided,   however,  that  the  Trustee  and  the  Trust
Administrator  shall not be  responsible  for the  accuracy  or  content  of any
certificate,  statement,  instrument, report, notice or other document furnished
by the Master Servicer or the Servicers pursuant to Articles III, IV and IX.

     No  provision of this  Agreement  shall be construed to relieve the Trustee
and the Trust Administrator from liability for its own negligent action, its own
negligent failure to act or its own willful misconduct; provided, however, that:

          (i)  Prior to the  occurrence  of an Event of  Default  and  after the
     curing of all such Events of Default  which may have  occurred,  the duties
     and  obligations  of the  Trustee  and the  Trust  Administrator  shall  be
     determined solely by the express provisions of this Agreement,  the Trustee
     and the Trust  Administrator shall not be liable except for the performance
     of such  duties  and  obligations  as are  specifically  set  forth in this
     Agreement,  no implied  covenants  or  obligations  shall be read into this
     Agreement  against  the  Trustee  and the Trust  Administrator  and, in the
     absence  of  bad  faith  on  the  part  of  the   Trustee   and  the  Trust
     Administrator,  the Trustee and the Trust  Administrator  may  conclusively
     rely, as to the truth of the statements and the correctness of the opinions
     expressed  therein,  upon any  certificates  or opinions  furnished  to the
     Trustee and the Trust Administrator,  and conforming to the requirements of
     this Agreement;

          (ii) The Trustee and the Trust  Administrator  shall not be personally
     liable with respect to any action taken, suffered or omitted to be taken by
     it  in  good  faith  in  accordance   with  the  direction  of  holders  of
     Certificates  which  evidence  in the  aggregate  not less  than 25% of the
     Voting  Interest  represented  by all  Certificates  relating  to the time,
     method and place of conducting any  proceeding for any remedy  available to
     the Trustee and the Trust  Administrator,  or exercising any trust or power
     conferred  upon  the  Trustee  and  the  Trust  Administrator,  under  this
     Agreement; and

          (iii) The Trustee and the Trust  Administrator shall not be liable for
     any  error  of  judgment  made in good  faith  by any of  their  respective
     Responsible  Officers,  unless it shall be proved  that the  Trustee or the
     Trust  Administrator or such Responsible  Officer,  as the case may be, was
     negligent in ascertaining the pertinent facts.

     None of the  provisions  contained  in this  Agreement  shall  require  the
Trustee or the Trust  Administrator to expend or risk its own funds or otherwise
incur  personal  financial  liability  in the  performance  of any of its duties
hereunder  or in the  exercise  of any of its  rights  or  powers  if  there  is
reasonable  ground  for  believing  that  repayment  of such  funds or  adequate
indemnity against such risk or liability is not reasonably assured to it.

Section 8.02.     Certain Matters Affecting the Trustee and the Trust
Administrator.

     Except as otherwise provided in Section 8.01:

          (i) Each of the Trustee and the Trust Administrator may rely and shall
     be  protected  in acting or  refraining  from acting  upon any  resolution,
     Officers'  Certificate,  certificate of auditors or any other  certificate,
     statement,  instrument,  opinion, report, notice, request,  consent, order,
     appraisal, bond or other paper or document believed by it to be genuine and
     to have been signed or presented by the proper party or parties;

          (ii) Each of the Trustee and the Trust  Administrator may consult with
     counsel,   and  any  Opinion  of  Counsel   shall  be  full  and   complete
     authorization  and protection in respect of any action taken or suffered or
     omitted by it hereunder in good faith and in  accordance  with such Opinion
     of Counsel;

          (iii)  Neither of the  Trustee  nor the Trust  Administrator  shall be
     personally  liable for any action taken,  suffered or omitted by it in good
     faith and  believed  by it to be  authorized  or within the  discretion  or
     rights or powers conferred upon it by this Agreement; and

          (iv) Each of the Trustee and the Trust  Administrator  may execute any
     of the trusts or powers  hereunder or perform any duties  hereunder  either
     directly or by or through agents or attorneys.

Section 8.03.     Neither Trustee nor Trust Administrator Required to
Make Investigation.

     Prior to the  occurrence  of an Event of  Default  hereunder  and after the
curing of all Events of Default which may have occurred, neither the Trustee nor
the Trust  Administrator shall be bound to make any investigation into the facts
or  matters  stated  in  any  resolution,  certificate,  statement,  instrument,
opinion,  report, notice, request,  consent,  order, appraisal,  bond, Mortgage,
Mortgage Note or other paper or document  (provided the same appears  regular on
its face),  unless  requested  in  writing  to do so by holders of  Certificates
evidencing in the aggregate not less than 51% of the Voting Interest represented
by all Certificates;  provided, however, that if the payment within a reasonable
time to the  Trustee  or the  Trust  Administrator  of the  costs,  expenses  or
liabilities  likely to be incurred by it in the making of such investigation is,
in the opinion of the Trustee or the Trust Administrator, not reasonably assured
to the Trustee or the Trust  Administrator by the security afforded to it by the
terms of this  Agreement,  the  Trustee or the Trust  Administrator  may require
reasonable  indemnity  against  such  expense or  liability as a condition to so
proceeding.  The reasonable expense of every such investigation shall be paid by
the Master Servicer or, if paid by the Trustee or the Trust Administrator, shall
be repaid by the Master Servicer upon demand.

Section 8.04.     Neither Trustee nor Trust Administrator Liable for
Certificates or Mortgage Loans.

     The  recitals  contained  herein and in the  Certificates  (other  than the
certificate  of  authentication  on the  Certificates)  shall  be  taken  as the
statements  of the Seller,  and neither the Trustee nor the Trust  Administrator
assumes  responsibility  as to the correctness of the same.  Neither the Trustee
nor the Trust  Administrator makes any representation for the correctness of the
same. Neither the Trustee nor the Trust  Administrator  makes any representation
as to the validity or sufficiency of this Agreement or of the Certificates or of
any Mortgage  Loan or related  document.  Subject to Section  2.04,  neither the
Trustee  nor  the  Trust  Administrator  shall  be  accountable  for  the use or
application by the Seller of any of the  Certificates or of the proceeds of such
Certificates,  or for the use or  application  of any funds  paid to the  Master
Servicer in respect of the Mortgage Loans deposited into the Certificate Account
by the Master  Servicer or, in its capacity as trustee,  for  investment  of any
such amounts.

Section 8.05.     Trustee and Trust Administrator May Own
Certificates.

     Each of the Trustee,  the Trust Administrator and any agent thereof, in its
individual  or  any  other  capacity,   may  become  the  owner  or  pledgee  of
Certificates  with the same rights it would have if it were not  Trustee,  Trust
Administrator or such agent.

Section 8.06.     The Master Servicer to Pay Fees and Expenses.

     The Master Servicer  covenants and agrees to pay to each of the Trustee and
the Trust Administrator from time to time, and each of the Trustee and the Trust
Administrator shall be entitled to receive, reasonable compensation (which shall
not be  limited  by any  provision  of law in  regard to the  compensation  of a
trustee of an express trust) for all services rendered by it in the execution of
the trusts  hereby  created and in the  exercise and  performance  of any of the
powers and duties  hereunder of the Trustee or the Trust  Administrator,  as the
case may be, and the Master  Servicer  will pay or reimburse  the Trustee or the
Trust  Administrator,  as the case may be, upon its  request for all  reasonable
expenses,  disbursements  and advances incurred or made by it in accordance with
any of the provisions of this Agreement  (including the reasonable  compensation
and the  expenses  and  disbursements  of its  counsel  and of all  persons  not
regularly in its employ)  except any such expense,  disbursement,  or advance as
may arise from its negligence or bad faith.

Section 8.07.     Eligibility Requirements.

     Each of the  Trustee  and the Trust  Administrator  hereunder  shall at all
times (i) be a corporation or association having its principal office in a state
and city  acceptable to the Seller,  organized and doing business under the laws
of such state or the United  States of  America,  authorized  under such laws to
exercise  corporate  trust powers,  having a combined  capital and surplus of at
least $50,000,000,  or shall be a member of a bank holding system, the aggregate
combined capital and surplus of which is at least $50,000,000, provided that its
separate capital and surplus shall at all times be at least the amount specified
in Section  310(a)(2)  of the Trust  Indenture  Act of 1939,  (ii) be subject to
supervision or examination by federal or state authority and (iii) have a credit
rating or be otherwise  acceptable  to the Rating  Agencies such that neither of
the Rating  Agencies would reduce their  respective  then current ratings of the
Certificates  (or have provided such security from time to time as is sufficient
to avoid such reduction) as evidenced in writing by each Rating Agency.  If such
corporation or  association  publishes  reports of condition at least  annually,
pursuant to law or to the requirements of the aforesaid supervising or examining
authority,  then for the  purposes  of this  Section  the  combined  capital and
surplus of such  corporation or  association  shall be deemed to be its combined
capital  and  surplus as set forth in its most  recent  report of  condition  so
published.  In case at any time the  Trustee  or the Trust  Administrator  shall
cease to be eligible in accordance  with the  provisions  of this Section,  such
entity shall resign  immediately in the manner and with the effect  specified in
Section 8.08.

Section 8.08.     Resignation and Removal.

     Either of the Trustee or the Trust Administrator may at any time resign and
be  discharged  from the  trust  hereby  created  by  giving  written  notice of
resignation to the Master  Servicer,  such  resignation to be effective upon the
appointment of a successor  trustee.  Upon receiving such notice of resignation,
the  Master  Servicer  shall  promptly  appoint a  successor  trustee by written
instrument, in duplicate, one copy of which instrument shall be delivered to the
resigning  entity and one copy to its successor.  If no successor  trustee shall
have been  appointed  and have  accepted  appointment  within 30 days  after the
giving  of  such  notice  of  resignation,   the  resigning   Trustee  or  Trust
Administrator,  as the  case  may  be,  may  petition  any  court  of  competent
jurisdiction for the appointment of a successor trustee or trust administrator.

     If at any time the  Trustee or the Trust  Administrator  shall  cease to be
eligible in  accordance  with the  provisions  of Section 8.07 and shall fail to
resign after written request for its resignation by the Master  Servicer,  or if
at any time the Trustee or the Trust  Administrator  shall  become  incapable of
acting,  or an order for relief  shall have been  entered in any  bankruptcy  or
insolvency  proceeding with respect to such entity, or a receiver of such entity
or of its property  shall be appointed,  or any public officer shall take charge
or  control of the  Trustee or the Trust  Administrator  or of the  property  or
affairs  of  the  Trustee  or  the  Trust   Administrator  for  the  purpose  of
rehabilitation,  conversion or liquidation, or the Master Servicer shall deem it
necessary  in order to  change  the  situs of the  Trust  Estate  for  state tax
reasons,  then the Master  Servicer  shall  remove the Trustee  and/or the Trust
Administrator,  as the case may be,  and  appoint  a  successor  trustee  and/or
successor trust administrator by written instrument,  in duplicate,  one copy of
which  instrument  shall be delivered to the Trustee or Trust  Administrator  so
removed and one copy to the successor trustee or successor trust  administrator,
as the case may be.

     The Holders of  Certificates  evidencing in the aggregate not less than 51%
of the  Voting  Interests  represented  by all  Certificates  (except  that  any
Certificate  registered  in the name of the Seller,  the Master  Servicer or any
affiliate  thereof  will not be taken into  account in  determining  whether the
requisite Voting Interests has been obtained) may at any time remove the Trustee
and/or the Trust  Administrator and appoint a successor by written instrument or
instruments,  in triplicate,  signed by such holders or their  attorneys-in-fact
duly authorized, one complete set of which instruments shall be delivered to the
Master  Servicer,  one complete set of which shall be delivered to the entity or
entities so removed and one  complete  set of which  shall be  delivered  to the
successor so appointed.

     Any  resignation or removal of the Trustee or the Trust  Administrator  and
appointment  of a successor  pursuant to any of the  provisions  of this Section
shall become  effective  upon  acceptance  of  appointment  by the  successor as
provided in Section 8.09.

Section 8.09.     Successor.

     Any  successor  trustee  or  successor  trust  administrator  appointed  as
provided in Section 8.08 shall  execute,  acknowledge  and deliver to the Master
Servicer and to its predecessor trustee or trust administrator,  as the case may
be, an  instrument  accepting  such  appointment  hereunder,  and  thereupon the
resignation or removal of the predecessor  trustee or trust  administrator shall
become  effective,  and  such  successor,  without  any  further  act,  deed  or
reconveyance,  shall become fully vested with all the rights, powers, duties and
obligations  of its  predecessor  hereunder,  with like effect as if  originally
named as  trustee  or trust  administrator,  as the  case  may be,  herein.  The
predecessor  trustee or trust  administrator  shall deliver to its successor all
Owner  Mortgage  Loan Files and  related  documents  and  statements  held by it
hereunder  (other  than any  Owner  Mortgage  Loan  Files at the time  held by a
Custodian,  which  Custodian  shall  become the agent of any  successor  trustee
hereunder), and the Seller, the Master Servicer and the predecessor entity shall
execute and deliver such  instruments and do such other things as may reasonably
be required for more fully and certainly vesting and confirming in the successor
trustee or successor trust  administrator,  as the case may be, all such rights,
powers,  duties and  obligations.  No  successor  shall  accept  appointment  as
provided in this Section  unless at the time of such  acceptance  such successor
shall be eligible under the provisions of Section 8.07

     Upon  acceptance of appointment by a successor as provided in this Section,
the Master Servicer shall mail notice of the succession of such trustee or trust
administrator  hereunder to all Holders of  Certificates  at their  addresses as
shown in the  Certificate  Register.  If the Master  Servicer fails to mail such
notice  within  ten days  after  acceptance  of the  successor  trustee or trust
administrator,  as the case may be, the successor trustee or trust administrator
shall cause such notice to be mailed at the expense of the Master Servicer.

Section 8.10.     Merger or Consolidation.

     Any Person into which either the Trustee or the Trust  Administrator may be
merged or converted or with which it may be  consolidated,  to which it may sell
or transfer its corporate trust business and assets as a whole or  substantially
as a whole or any Person resulting from any merger, sale,  transfer,  conversion
or  consolidation  to which the  Trustee or the Trust  Administrator  shall be a
party,  or any Person  succeeding  to the business of such entity,  shall be the
successor of the Trustee or Trust Administrator,  as the case may be, hereunder;
provided,  however,  that (i) such Person shall be eligible under the provisions
of Section 8.07, without the execution or filing of any paper or any further act
on the  part of any of the  parties  hereto,  anything  herein  to the  contrary
notwithstanding,  and (ii) the Trustee or the Trust  Administrator,  as the case
may be,  shall  deliver  an  Opinion  of  Counsel  to the  Seller and the Master
Servicer to the effect that such merger,  consolidation,  sale or transfer  will
not subject  either the  Upper-Tier  REMIC or the  Lower-Tier  REMIC to federal,
state or local tax or cause either the Upper-Tier  REMIC or the Lower-Tier REMIC
to fail to qualify  as a REMIC,  which  Opinion of Counsel  shall be at the sole
expense of the Trustee or the Trust Administrator, as the case may be.

Section 8.11.     Authenticating Agent.

     The Trust Administrator may appoint an Authenticating Agent, which shall be
authorized  to act  on  behalf  of the  Trust  Administrator  in  authenticating
Certificates. Wherever reference is made in this Agreement to the authentication
of  Certificates  by  the  Trust  Administrator  or  the  Trust  Administrator's
countersignature,  such reference shall be deemed to include  authentication  on
behalf of the Trust Administrator by the Authenticating  Agent and a certificate
of  authentication  executed  on  behalf  of  the  Trust  Administrator  by  the
Authenticating  Agent. The Authenticating Agent must be acceptable to the Seller
and the Master  Servicer and must be a corporation  organized and doing business
under  the laws of the  United  States  of  America  or of any  state,  having a
principal  office and place of  business in a state and city  acceptable  to the
Seller and the Master  Servicer,  having a combined  capital  and  surplus of at
least $15,000,000, authorized under such laws to do a trust business and subject
to supervision or examination by federal or state authorities.

     Any  corporation  into  which  the  Authenticating  Agent  may be merged or
converted or with which it may be  consolidated,  or any  corporation  resulting
from any merger,  conversion or consolidation to which the Authenticating  Agent
shall be a party, or any corporation succeeding to the corporate agency business
of the  Authenticating  Agent,  shall be the  Authenticating  Agent  without the
execution  or filing of any  paper or any  further  act on the part of the Trust
Administrator or the Authenticating Agent.

     The Authenticating Agent may at any time resign by giving at least 30 days'
advance written notice of resignation to the Trustee,  the Trust  Administrator,
the Seller  and the Master  Servicer.  The Trust  Administrator  may at any time
terminate  the  agency  of the  Authenticating  Agent by giving  written  notice
thereof to the  Authenticating  Agent, the Seller and the Master Servicer.  Upon
receiving a notice of resignation or upon such a termination,  or in case at any
time the Authenticating  Agent shall cease to be eligible in accordance with the
provisions of this Section 8.11, the Trust Administrator  promptly shall appoint
a  successor  Authenticating  Agent,  which  shall be  acceptable  to the Master
Servicer,  and shall give written notice of such appointment to the Seller,  and
shall mail notice of such appointment to all  Certificateholders.  Any successor
Authenticating  Agent upon acceptance of its appointment  hereunder shall become
vested  with  all  the  rights,  powers,  duties  and  responsibilities  of  its
predecessor hereunder, with like effect as if originally named as Authenticating
Agent  herein.  No  successor  Authenticating  Agent shall be  appointed  unless
eligible under the provisions of this Section 8.11.

     The Authenticating  Agent shall have no responsibility or liability for any
action  taken by it as such at the  direction  of the Trust  Administrator.  Any
reasonable compensation paid to the Authenticating Agent shall be a reimbursable
expense under Section 8.06.

Section 8.12.     Separate Trustees and Co-Trustees.

     The  Trustee  shall have the power from time to time to appoint one or more
persons or corporations  to act either as co-trustees  jointly with the Trustee,
or as separate  trustees,  for the purpose of holding title to,  foreclosing  or
otherwise  taking  action with  respect to any  Mortgage  Loan outside the state
where the Trustee  has its  principal  place of  business,  where such  separate
trustee or  co-trustee  is necessary or advisable  (or the Trustee is advised by
the Master  Servicer  that such  separate  trustee or co-trustee is necessary or
advisable) under the laws of any state in which a Mortgaged  Property is located
or for the purpose of otherwise conforming to any legal requirement, restriction
or  condition  in any state in which a  Mortgaged  Property is located or in any
state in which any portion of the Trust Estate is located.  The Master  Servicer
shall advise the Trustee when, in its good faith opinion,  a separate trustee or
co-trustee  is necessary or advisable  as  aforesaid.  The separate  trustees or
co-trustees  so  appointed  shall  be  trustees  for the  benefit  of all of the
Certificateholders  and shall have such powers,  rights and remedies as shall be
specified in the  instrument of  appointment;  provided,  however,  that no such
appointment  shall, or shall be deemed to,  constitute the appointee an agent of
the  Trustee.  The  Seller  and the  Master  Servicer  shall  join  in any  such
appointment,  but such joining shall not be necessary for the  effectiveness  of
such appointment.

     Every separate  trustee and co-trustee  shall,  to the extent  permitted by
law, be appointed and act subject to the following provisions and conditions:

          (i) all powers,  duties,  obligations  and rights  conferred  upon the
     Trustee, in respect of the receipt,  custody and payment of moneys shall be
     exercised solely by the Trustee;

          (ii) all other rights,  powers,  duties and  obligations  conferred or
     imposed upon the Trustee  shall be conferred or imposed upon and  exercised
     or  performed  by the  Trustee  and such  separate  trustee  or  co-trustee
     jointly,  except to the extent  that under any law of any  jurisdiction  in
     which any  particular  act or acts are to be performed  (whether as Trustee
     hereunder  or as successor to the Master  Servicer  hereunder)  the Trustee
     shall be  incompetent  or unqualified to perform such act or acts, in which
     event such rights, powers, duties and obligations (including the holding of
     title to the Trust Estate or any portion thereof in any such  jurisdiction)
     shall be exercised and performed by such separate trustee or co-trustee;

          (iii) no separate trustee or co-trustee  hereunder shall be personally
     liable by reason of any act or  omission of any other  separate  trustee or
     co-trustee hereunder; and

          (iv) the Trustee may at any time accept the  resignation  of or remove
     any separate  trustee or co-trustee so appointed by it, if such resignation
     or removal does not violate the other terms of this Agreement.

     Any notice,  request or other  writing given to the Trustee shall be deemed
to have been given to each of the then  separate  trustees and  co-trustees,  as
effectively  as if  given  to each of  them.  Every  instrument  appointing  any
separate trustee, co-trustee, or custodian shall refer to this Agreement and the
conditions  of this  Article.  Each separate  trustee and  co-trustee,  upon its
acceptance of the trusts conferred, shall be vested with the estates or property
specified in its instrument of appointment,  either jointly with the Trustee, or
separately,  as may be provided  therein,  subject to all the provisions of this
Agreement,  specifically including every provision of this Agreement relating to
the conduct of,  affecting  the liability  of, or affording  protection  to, the
Trustee. Every such instrument shall be furnished to the Trustee.

     Any separate trustee, co-trustee, or custodian may, at any time, constitute
the Trustee,  its agent or attorney-in-fact,  with full power and authority,  to
the extent not  prohibited  by law,  to do any lawful act under or in respect of
this  Agreement  on its  behalf  and in its name.  If any  separate  trustee  or
co-trustee shall die, become incapable of acting,  resign or be removed,  all of
its  estates,  properties,  rights,  remedies  and  trusts  shall vest in and be
exercised by the Trustee to the extent permitted by law, without the appointment
of a new or successor trustee.

     No separate  trustee or co-trustee  hereunder shall be required to meet the
terms of eligibility as a successor  trustee under Section 8.07 hereunder and no
notice to  Certificateholders of the appointment thereof shall be required under
Section 8.09 hereof.

     The  Trustee  agrees to  instruct  its  co-trustees,  if any, to the extent
necessary to fulfill such entity's obligations hereunder.

     The  Master   Servicer  shall  pay  the  reasonable   compensation  of  the
co-trustees to the extent,  and in accordance  with the standards,  specified in
Section 8.06 hereof.

Section 8.13.     Appointment of Custodians.

     The Trust  Administrator may at any time on or after the Closing Date, with
the  consent  of the  Master  Servicer  and  the  Seller,  appoint  one or  more
Custodians  to hold all or a portion of the Owner  Mortgage  Loan Files as agent
for the Trust Administrator,  by entering into a Custodial Agreement. Subject to
this Article VIII,  the Trust  Administrator  agrees to comply with the terms of
each Custodial Agreement and to enforce the terms and provisions thereof against
the Custodian for the benefit of the Certificateholders. Each Custodian shall be
a depository  institution  subject to supervision by federal or state authority,
shall have a combined  capital and surplus of at least  $10,000,000 and shall be
qualified  to do  business  in the  jurisdiction  in which it  holds  any  Owner
Mortgage Loan File. Each Custodial  Agreement may be amended only as provided in
Section 10.01(a).

Section 8.14.     Tax Matters; Compliance with REMIC Provisions.

     (a) Each of the Trustee,  the Trust  Administrator  and the Master Servicer
covenants  and agrees  that it shall  perform its duties  hereunder  in a manner
consistent with the REMIC  Provisions and shall not knowingly take any action or
fail to take any action  that would (i)  affect the  determination  of the Trust
Estate's  status as two separate  REMICs;  or (ii) cause the  imposition  of any
federal, state or local income,  prohibited  transaction,  contribution or other
tax on either the Upper-Tier  REMIC,  the Lower-Tier  REMIC or the Trust Estate.
The Master Servicer,  or, in the case of any tax return or other action required
by  law  to  be  performed  directly  by  the  Trust  Administrator,  the  Trust
Administrator,  shall (i) prepare or cause to be  prepared,  timely  cause to be
signed  by the  Trustee  and  file or  cause  to be  filed  annual  federal  and
applicable  state and local income tax returns for each of the Upper-Tier  REMIC
and the  Lower-Tier  REMIC  using a calendar  year as the  taxable  year and the
accrual method of accounting;  (ii) in the first such federal tax returns, make,
or  cause  to be  made,  elections  satisfying  the  requirements  of the  REMIC
Provisions, on behalf of the Trust Estate, to treat each of the Upper-Tier REMIC
and the  Lower-Tier  REMIC as a REMIC;  (iii) prepare,  execute and forward,  or
cause to be prepared,  executed and  forwarded,  to the  Certificateholders  all
information reports or tax returns required with respect to the Trust Estate, as
and when required to be provided to the Certificateholders,  and to the Internal
Revenue  Service  and  any  other  relevant  governmental  taxing  authority  in
accordance with the REMIC Provisions and any other applicable federal,  state or
local  laws,  including  without  limitation  information  reports  relating  to
"original  issue  discount"  and "market  discount" as defined in the Code based
upon the issue  prices,  prepayment  assumption  and cash flows  provided by the
Seller to the Trust Administrator and calculated on a monthly basis by using the
issue prices of the Certificates;  (iv) make available information necessary for
the  application  of any tax imposed on  transferors  of residual  interests  to
"disqualified  organizations"  (as  defined in the REMIC  Provisions);  (v) file
Forms SS-4 and 8811 and  respond to  inquiries  by  Certificateholders  or their
nominees concerning  information returns,  reports or tax returns; (vi) maintain
(or cause to be  maintained  by the  Servicers)  such  records  relating  to the
Upper-Tier  REMIC and the  Lower-Tier  REMIC,  including  but not limited to the
income, expenses, individual Mortgage Loans (including REO Mortgage Loans, other
assets and  liabilities  of each REMIC,  and the fair market  value and adjusted
basis of the  property  of each REMIC  determined  at such  intervals  as may be
required by the Code,  as may be necessary to prepare the  foregoing  returns or
information reports; (vii) exercise reasonable care not to allow the creation of
any  "interests" in either the Upper-Tier  REMIC or the Lower-Tier  REMIC within
the  meaning  of  Code  Section  860D(a)(2)  other  than  the  interests  in the
Upper-Tier REMIC  represented by the Class A-1, Class A-2, Class A-3, Class A-4,
Class A-5, Class A-6,  Class A-7, Class A-8, Class A-9, Class A-WIO,  Class A-PO
and Class A-R  Certificates,  the Class M Certificates  and the Class B-l, Class
B-2,  Class B-3, Class B-4 and Class B-5  Certificates  and the interests in the
Lower-Tier  REMIC  represented by the Class A-L1,  Class A-L2, Class A-L9, Class
A-LPO, A-LIO, Class A-LUR, Class B-L1, Class B-L2, Class B-L3, Class B-L4, Class
B-L5 and Class M-L Interests  and the Class A-LR  Certificate;  (viii)  exercise
reasonable  care not to allow the  occurrence of any  "prohibited  transactions"
within the meaning of Code Section  860F(a),  unless the Master  Servicer  shall
have  provided an Opinion of Counsel to the Trustee and the Trust  Administrator
that such  occurrence  would not (a)  result in a taxable  gain,  (b)  otherwise
subject either the Upper-Tier  REMIC or Lower-Tier  REMIC or the Trust Estate to
tax or (c) cause the Trust  Estate to fail to  qualify as two  separate  REMICs;
(ix) exercise  reasonable  care not to allow either the Upper-Tier  REMIC or the
Lower-Tier  REMIC to receive  income  from the  performance  of services or from
assets not permitted under the REMIC  Provisions to be held by a REMIC;  (x) pay
(on behalf of the Upper-Tier  REMIC or the  Lower-Tier  REMIC) the amount of any
federal income tax, including, without limitation, prohibited transaction taxes,
taxes  on  net  income  from   foreclosure   property,   and  taxes  on  certain
contributions  to a REMIC after the Startup Day, imposed on the Upper-Tier REMIC
or Lower-Tier  REMIC,  as the case may be, when and as the same shall be due and
payable (but such obligation  shall not prevent the Master Servicer or any other
appropriate  Person from contesting any such tax in appropriate  proceedings and
shall not prevent the Master Servicer from withholding or depositing  payment of
such tax, if permitted  by law,  pending the outcome of such  proceedings);  and
(xi) if  required  or  permitted  by the Code and  applicable  law,  act as "tax
matters  person" for the  Upper-Tier  REMIC or the  Lower-Tier  REMIC within the
meaning of Treasury Regulations Section 1.860F-4(d),  and the Master Servicer is
hereby  designated  as agent of the Class A-R and Class A-LR  Certificateholders
for such purpose (or if the Master Servicer is not so permitted,  the Holders of
the  Class A-R and Class  A-LR  Certificates  shall be tax  matters  persons  in
accordance with the REMIC Provisions).  The Master Servicer shall be entitled to
be  reimbursed  pursuant  to Section  3.02 for any taxes paid by it  pursuant to
clause (x) of the preceding  sentence,  except to the extent that such taxes are
imposed as a result of the bad faith, willful misfeasance or gross negligence of
the  Master  Servicer  in the  performance  of its  obligations  hereunder.  The
Trustee's sole duties with respect to the Upper-Tier  REMIC and Lower Tier REMIC
are to sign the tax returns  referred  to in clause (i) of the second  preceding
sentence and to comply with written  directions  from the Master Servicer or the
Trust Administrator.

     In order to enable  the Master  Servicer,  the Trust  Administrator  or the
Trustee,  as the case may be, to  perform  its  duties as set forth  above,  the
Seller shall provide, or cause to be provided, to the Master Servicer within ten
days after the Closing  Date all  information  or data that the Master  Servicer
determines to be relevant for tax purposes to the valuations and offering prices
of the Certificates, including, without limitation, the price, yield, prepayment
assumption and projected  cash flows of each Class and Subclass of  Certificates
and the Mortgage Loans in the aggregate. Thereafter, the Seller shall provide to
the Master Servicer, the Trust Administrator or the Trustee, as the case may be,
promptly upon request therefor, any such additional information or data that the
Master Servicer, the Trust Administrator or the Trustee, as the case may be, may
from time to time, request in order to enable the Master Servicer to perform its
duties as set forth above.  The Seller hereby  indemnifies the Master  Servicer,
the Trust  Administrator  or the  Trustee,  as the case may be, for any  losses,
liabilities,  damages,  claims or  expenses  of the Master  Servicer,  the Trust
Administrator or the Trustee arising from any errors or  miscalculations  by the
Master Servicer, the Trust Administrator or the Trustee pursuant to this Section
that  result  from any  failure  of the  Seller  to  provide,  or to cause to be
provided,  accurate  information  or  data to the  Master  Servicer,  the  Trust
Administrator or the Trustee,  as the case may be, on a timely basis. The Master
Servicer hereby indemnifies the Seller, the Trust  Administrator and the Trustee
for any losses,  liabilities,  damages,  claims or  expenses of the Seller,  the
Trust  Administrator or the Trustee arising from the Master  Servicer's  willful
misfeasance,  bad faith or gross  negligence  in  preparing  any of the federal,
state and local tax  returns of the  Upper-Tier  REMIC and  Lower-Tier  REMIC as
described above. In the event that the Trust  Administrator  prepares any of the
federal, state and local tax returns of the Upper-Tier REMIC or Lower-Tier REMIC
as described above, the Trust  Administrator  hereby indemnifies the Seller, the
Master Servicer and the Trustee for any losses, liabilities,  damages, claims or
expenses of the Seller,  the Master  Servicer  or the Trustee  arising  from the
Trust Administrator's willful misfeasance, bad faith or negligence in connection
with such preparation.

     (b) Notwithstanding  anything in this Agreement to the contrary, the Master
Servicer,  the Trust Administrator and the Trustee shall pay from its own funds,
without  any  right  of  reimbursement   therefor,  the  amount  of  any  costs,
liabilities  and  expenses  incurred  by the Trust  Estate  (including,  without
limitation,  any and all federal,  state or local taxes, including taxes imposed
on "prohibited  transactions" within the meaning of the REMIC Provisions) if and
to the extent that such costs,  liabilities and expenses arise from a failure of
the Master Servicer,  the Trust Administrator or the Trustee,  respectively,  to
perform its obligations under this Section 8.14.

Section 8.15.     Monthly Advances.

     In the  event  that  Norwest  Mortgage  fails  to make a  Periodic  Advance
required to be made pursuant to the Norwest Servicing Agreement on or before the
Distribution  Date,  the Trust  Administrator  shall make a Periodic  Advance as
required by Section  3.03 hereof;  provided,  however,  the Trust  Administrator
shall not be required to make such Periodic  Advances if prohibited by law or if
it determines that such Periodic Advance would be a Nonrecoverable Advance. With
respect  to those  Periodic  Advances  which  should  have been made by  Norwest
Mortgage,  the  Trust  Administrator  shall be  entitled,  pursuant  to  Section
3.02(a)(i),  (ii) or (v) hereof,  to be reimbursed from the Certificate  Account
for Periodic Advances and Nonrecoverable Advances made by it.

ARTICLE IX

TERMINATION

Section 9.01.     Termination upon Purchase by the
Seller or Liquidation of All Mortgage Loans.

     Subject to Section 9.02, the respective obligations and responsibilities of
the Seller, the Master Servicer, the Trust Administrator and the Trustee created
hereby  (other than the  obligation of the Trust  Administrator  to make certain
payments  after  the  Final  Distribution  Date  to  Certificateholders  and the
obligation of the Master  Servicer to send certain  notices as  hereinafter  set
forth and the tax  reporting  obligations  under  Sections 4.05 and 8.14 hereof)
shall  terminate  upon  the  last  action  required  to be  taken  by the  Trust
Administrator  on the  Final  Distribution  Date  pursuant  to this  Article  IX
following  the earlier of (i) the purchase by the Seller of all  Mortgage  Loans
and all property acquired in respect of any Mortgage Loan remaining in the Trust
Estate at a price equal to the sum of (x) 100% of the unpaid  principal  balance
of each  Mortgage  Loan  (other  than any REO  Mortgage  Loan)  as of the  Final
Distribution  Date,  and (y) the fair  market  value of the  Mortgaged  Property
related to any REO Mortgage Loan (as determined by the Master Servicer as of the
close of business on the third  Business Day next  preceding the date upon which
notice of any such  termination is furnished to  Certificateholders  pursuant to
the third paragraph of this Section 9.01),  plus any accrued and unpaid interest
through the last day of the month  preceding  the month of such  purchase at the
applicable   Mortgage  Interest  Rate  and  (ii)  the  final  payment  or  other
liquidation  (or any advance with  respect  thereto) of the last  Mortgage  Loan
remaining in the Trust Estate  (including  for this purpose the discharge of any
Mortgagor  under a defaulted  Mortgage Loan on which a Servicer is not obligated
to foreclose due to environmental impairment) or the disposition of all property
acquired upon  foreclosure  or deed in lieu of foreclosure of any Mortgage Loan;
provided,  however,  that in no event shall the trust  created  hereby  continue
beyond the  expiration  of 21 years from the death of the last  survivor  of the
descendants  of Joseph P. Kennedy,  the late  ambassador of the United States to
the Court of St. James, living on the date hereof.

     The right of the  Seller to  purchase  all the  assets of the Trust  Estate
pursuant to clause (i) of the  preceding  paragraph  are subject to Section 9.02
and conditioned upon the Pool Scheduled  Principal Balance of the Mortgage Loans
as of the  Final  Distribution  Date  being  less than the  amount  set forth in
Section 11.25. In the case of any purchase by the Seller pursuant to said clause
(i),  the Seller  shall  provide to the Trust  Administrator  the  certification
required by Section 3.04 and the Trust  Administrator  and the Custodian  shall,
promptly  following  payment of the  purchase  price,  release to the Seller the
Owner Mortgage Loan Files pertaining to the Mortgage Loans being purchased.

     Notice of any termination,  specifying the Final  Distribution  Date (which
shall be a date that  would  otherwise  be a  Distribution  Date) upon which the
Certificateholders  may surrender their Certificates to the Trust  Administrator
for payment of the final distribution and cancellation,  shall be given promptly
by the Master  Servicer (if it is exercising its right to purchase the assets of
the Trust Estate) or by the Trust Administrator (in any other case) by letter to
Certificateholders  mailed not earlier than the 15th day of the month  preceding
the month of such final distribution and not later than the twentieth day of the
month of such final distribution specifying (A) the Final Distribution Date upon
which  final  payment of the  Certificates  will be made upon  presentation  and
surrender  of  Certificates  at the office or agency of the Trust  Administrator
therein  designated,  (B) the amount of any such final  payment and (C) that the
Record Date otherwise  applicable to such  Distribution  Date is not applicable,
payments  being made (except in the case of any Class A Certificate  surrendered
on a prior  Distribution  Date pursuant to Section 4.01) only upon  presentation
and  surrender  of the  Certificates  at  the  office  or  agency  of the  Trust
Administrator  therein  specified.  If the Master  Servicer is obligated to give
notice to  Certificateholders  as  aforesaid,  it shall give such  notice to the
Trust  Administrator  and the  Certificate  Registrar at the time such notice is
given to  Certificateholders.  In the event  such  notice is given by the Master
Servicer,  the Master  Servicer shall deposit in the  Certificate  Account on or
before the Final  Distribution  Date in  immediately  available  funds an amount
equal to the purchase price for the assets of the Trust Estate computed as above
provided.  Failure to give notice of termination  as described  herein shall not
entitle a  Certificateholder  to any interest beyond the interest payable on the
Final Distribution Date.

     Upon   presentation   and   surrender  of  the   Certificates,   the  Trust
Administrator shall cause to be distributed to  Certificateholders  on the Final
Distribution  Date in proportion  to their  respective  Percentage  Interests an
amount equal to (i) as to the Subclasses of Class A Certificates, the respective
Class A Subclass  Principal  Balance  together with any related Class A Subclass
Unpaid  Interest  Shortfall  and one month's  interest in an amount equal to the
respective  Class A Subclass  Interest  Accrual  Amount,  (ii) as to the Class M
Certificates,  the Class M Principal  Balance  together with any related Class M
Unpaid Interest  Shortfall and one month's  interest at the Class M Pass-Through
Rate on the Class M Principal  Balance,  (iii) as to the  Subclasses  of Class B
Certificates,  the respective Class B Subclass  Principal  Balance together with
any related Class B Subclass Unpaid Interest  Shortfall and one month's interest
in an amount equal to the respective  Class B Subclass  Interest  Accrual Amount
and (iv) as to the Class A-R and Class A-LR Certificates,  the amounts,  if any,
which  remain  on  deposit  in  the  Upper-Tier   Certificate  Account  and  the
Certificate  Account,  respectively (other than amounts retained to meet claims)
after  application  pursuant to clauses (i), (ii) and (iii) above and payment to
the Master Servicer of any amounts it is entitled as  reimbursement or otherwise
hereunder. Such amount shall be distributed in respect of interest and principal
in respect of the  Uncertificated  Lower-Tier  Interests  in the same amounts as
distributed  to their  Corresponding  Upper-Tier  Class or Classes in the manner
specified in Section  4.01(a)(ii).  Notwithstanding the foregoing,  if the price
paid pursuant to clause (i) of the first  paragraph of this Section 9.01,  after
reimbursement to the Servicers,  the Master Servicer and the Trust Administrator
of any Periodic  Advances,  is insufficient to pay in full the amounts set forth
in clauses  (i),  (ii) and (iii) of this  paragraph,  then any  shortfall in the
amount  available for distribution to  Certificateholders  shall be allocated in
reduction of the amounts otherwise  distributable on the Final Distribution Date
in the same manner as Realized Losses are allocated pursuant to Sections 4.02(b)
and 4.02(g) hereof. Such distribution on the Final Distribution Date shall be in
lieu of the distribution otherwise required to be made on such Distribution Date
in respect of each Class of Certificates.

     In the event that all of the  Certificateholders  shall not surrender their
Certificates  for final payment and  cancellation  within three months following
the Final  Distribution Date, the Trust  Administrator  shall on such date cause
all  funds,  if  any,  in the  Certificate  Account  not  distributed  in  final
distribution to Certificateholders to be withdrawn therefrom and credited to the
remaining  Certificateholders  by  depositing  such funds in a  separate  escrow
account for the benefit of such Certificateholders,  and the Master Servicer (if
it exercised  its right to purchase the assets of the Trust Estate) or the Trust
Administrator  (in any other  case)  shall give a second  written  notice to the
remaining  Certificateholders  to surrender their  Certificates for cancellation
and receive the final distribution with respect thereto.  If within three months
after the second notice all the Certificates shall not have been surrendered for
cancellation, the Trust Administrator may take appropriate steps, or may appoint
an agent to take appropriate steps, to contact the remaining  Certificateholders
concerning  surrender of their Certificates,  and the cost thereof shall be paid
out of the funds on deposit in such escrow account.

Section 9.02.     Additional Termination Requirements.

     In the event of a termination  of the Trust Estate upon the exercise by the
Seller of its  purchase  option as provided in Section  9.01,  the Trust  Estate
shall be terminated in accordance  with the following  additional  requirements,
unless the Trust  Administrator has received an Opinion of Counsel to the effect
that  any  other  manner  of  termination   (i)  will  constitute  a  "qualified
liquidation"   of  the  Trust   Estate   within  the  meaning  of  Code  Section
860F(a)(4)(A)  and (ii) will not  subject  either  the  Upper-Tier  REMIC or the
Lower-Tier  REMIC to federal tax or cause the Trust Estate to fail to qualify as
two separate REMICs at any time that any Certificates are outstanding:

          (i) The notice given by the Master  Servicer  under Section 9.01 shall

time by the  Seller,  the  Master  Servicer,  the  Trust  Administrator  and the
Trustee,  without the consent of any of the Certificateholders,  (i) to cure any
ambiguity or mistake,  (ii) to correct or supplement  any  provisions  herein or
therein which may be inconsistent  with any other provisions  herein or therein,
(iii) to modify,  eliminate  or add to any of its  provisions  to such extent as
shall be  necessary  to maintain  the  qualification  of the Trust Estate as two
separate REMICs at all times that any  Certificates  are outstanding or to avoid
or minimize the risk of the  imposition  of any federal tax on the Trust Estate,
the Upper-Tier  REMIC or the Lower-Tier REMIC pursuant to the Code that would be
a claim  against the Trust  Estate,  provided that (a) the Trustee and the Trust
Administrator have received an Opinion of Counsel to the effect that such action
is necessary or desirable to maintain such qualification or to avoid or minimize
the risk of the  imposition  of any such tax and (b) such  action  shall not, as
evidenced by such Opinion of Counsel,  adversely  affect in any material respect
the interests of any Certificateholder,  (iv) to change the timing and/or nature
of deposits into the  Upper-Tier  Certificate  Account and  Certificate  Account
provided  that (a) such change shall not, as evidenced by an Opinion of Counsel,
adversely affect in any material respect the interests of any  Certificateholder
and (b) such change shall not adversely  affect the  then-current  rating of the
Certificates  as evidenced  by a letter from each Rating  Agency to such effect,
(v) to modify,  eliminate or add to the  provisions of Section 5.02 or any other
provisions hereof  restricting  transfer of the Certificates,  provided that the
Master  Servicer  for  purposes  of  Section  5.02  has  determined  in its sole
discretion that any such  modifications to this Agreement will neither adversely
affect the rating on the  Certificates  nor give rise to a risk that  either the
Upper-Tier REMIC or the Lower-Tier REMIC or any of the  Certificateholders  will
be subject to a tax caused by a transfer to a non-permitted  transferee and (vi)
to make any other provisions with respect to matters or questions  arising under
this  Agreement  or such  Custodial  Agreement  which  shall  not be  materially
inconsistent  with the provisions of this  Agreement,  provided that such action
shall  not,  as  evidenced  by an Opinion of  Counsel,  adversely  affect in any
material respect the interests of any Certificateholder.

     This Agreement or any Custodial  Agreement may also be amended from time to
time by the Seller, the Master Servicer, the Trust Administrator and the Trustee
with the consent of the Holders of Certificates  evidencing in the aggregate not
less than 66-2/3% of the aggregate Voting Interests of each Class or Subclass of
Certificates  affected  thereby for the purpose of adding any  provisions  to or
changing in any manner or eliminating any of the provisions of this Agreement or
such Custodial Agreement or of modifying in any manner the rights of the Holders
of  Certificates  of such Class or  Subclass;  provided,  however,  that no such
amendment  shall (i) reduce in any manner the amount of, or delay the timing of,
payments  received on Mortgage Loans which are required to be distributed on any
Certificate  without  the  consent  of the  Holder  of  such  Certificate,  (ii)
adversely  affect  in any  material  respect  the  interest  of the  Holders  of
Certificates  of any Class or Subclass in a manner  other than as  described  in
clause (i) hereof without the consent of Holders of  Certificates  of such Class
or  Subclass  evidencing,  as  to  such  Class  or  Subclass,  Voting  Interests
aggregating  not less than 66-2/3% or (iii) reduce the  aforesaid  percentage of
Certificates  of any Class or  Subclass  the  Holders of which are  required  to
consent  to any such  amendment,  without  the  consent  of the  Holders  of all
Certificates of such Class or Subclass then outstanding.

     Notwithstanding  any  contrary  provision  of this  Agreement,  neither the
Trustee  nor the Trust  Administrator  shall  consent to any  amendment  to this
Agreement  unless it shall  have  first  received  an  Opinion of Counsel to the
effect that such amendment  will not subject either the Upper-Tier  REMIC or the
Lower-Tier  REMIC to tax or cause either the Upper-Tier  REMIC or the Lower-Tier
REMIC  to fail to  qualify  as a REMIC at any time  that  any  Certificates  are
outstanding.

     Promptly  after the  execution of any  amendment  requiring  the consent of
Certificateholders,  the Trust Administrator shall furnish written  notification
of the substance of such amendment to each Certificateholder.

     It shall not be necessary for the consent of Certificateholders  under this
Section 10.01(a) to approve the particular form of any proposed  amendment,  but
it shall be sufficient if such consent shall approve the substance thereof.  The
manner of obtaining  such consents and of evidencing  the  authorization  of the
execution  thereof by  Certificateholders  shall be  subject to such  reasonable
regulations as the Trust Administrator may prescribe.

     (b)  Notwithstanding  any contrary provision of this Agreement,  the Master
Servicer may, from time to time,  amend Schedule I hereto without the consent of
any  Certificateholder,  the  Trust  Administrator  or  the  Trustee;  provided,
however,  (i) that such  amendment  does not conflict with any provisions of the
related Servicing Agreement,  (ii) that the related Servicing Agreement provides
for the remittance of each type of Unscheduled  Principal  Receipts  received by
such Servicer during the Applicable  Unscheduled Principal Receipt Period (as so
amended) related to each  Distribution Date to the Master Servicer no later than
the 24th day of the month in which such  Distribution Date occurs and (iii) that
such amendment is for the purpose of:

          (a)  changing the Applicable  Unscheduled Principal Receipt Period for
               Exhibit F-1  Mortgage  Loans to a Mid-Month  Receipt  Period with
               respect to all Unscheduled Principal Receipts; or

          (b)  changing the Applicable  Unscheduled Principal Receipt Period for
               all  Mortgage  Loans  serviced  by any  Servicer  to a  Mid-Month
               Receipt  Period  with  respect  to  Full  Unscheduled   Principal
               Receipts  and to a Prior Month  Receipt  Period  with  respect to
               Partial Unscheduled Principal Receipts.

shall be promptly forwarded to the Trust Administrator.

an  original,  and  such  counterparts  shall  constitute  but one and the  same
instrument.

terminate   this   Agreement   or   the   Trust   Estate,   nor   entitle   such
Certificateholder's  legal  representatives  or heirs to claim an  accounting or
take any action or  proceeding in any court for a partition or winding up of the
Trust Estate,  nor otherwise  affect the rights,  obligations and liabilities of
the parties hereto or any of them.

by virtue of its status as a Certificateholder,  shall have any right to vote or
in any manner  otherwise  control  the  operation  and  management  of the Trust
Estate, or the obligations of the parties hereto,  nor shall anything herein set
forth,  or  contained  in the terms of the  Certificates,  be construed so as to
constitute the Certificateholders from time to time as partners or members of an
association, nor shall any Certificateholder be under any liability to any third
person by reason of any action taken by the parties to this  Agreement  pursuant
to any provision hereof.

     No Certificateholder,  solely by virtue of its status as Certificateholder,
shall have any right by virtue or by availing of any provision of this Agreement
to institute any suit, action or proceeding in equity or at law upon or under or
with respect to this Agreement,  unless such Holder  previously shall have given
to the Trust  Administrator  a written notice of default and of the  continuance
thereof, as hereinbefore  provided,  and unless also the Holders of Certificates
evidencing  not  less  than  25%  of  the  Voting  Interest  represented  by all
Certificates  shall have made written  request upon the Trust  Administrator  to
institute such action, suit or proceeding in its own name as Trust Administrator
hereunder  and shall have  offered to the Trust  Administrator  such  reasonable
indemnity as it may require  against the cost,  expenses and  liabilities  to be
incurred therein or thereby, and the Trust Administrator,  for 60 days after its
receipt of such notice, request and offer of indemnity,  shall have neglected or
refused to institute any such action,  suit or proceeding;  it being  understood
and intended,  and being  expressly  covenanted by each  Certificateholder  with
every other  Certificateholder and the Trust Administrator,  that no one or more
Holders of Certificates shall have any right in any manner whatever by virtue or
by availing of any provision of this  Agreement to affect,  disturb or prejudice
the  rights of the  Holders of any other of such  Certificates,  or to obtain or
seek to obtain  priority  over or  preference  to any other such  Holder,  or to
enforce any right under this Agreement, except in the manner herein provided and

provisions of which is set forth hereinafter.  To the extent not defined herein,
the  capitalized  terms used herein have the meanings  ascribed to such terms in
the  Agreement.  This  Certificate  is issued under and is subject to the terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such

is  registered  at the close of business on the last  Business  Day of the month
preceding the month of such  distribution,  in an amount equal to the product of
the Percentage  Interest  evidenced by this Certificate and the Class A Subclass
Distribution Amount for the Class A-1 Certificates required to be distributed to
Holders  of  Class  A-1  Certificates  on such  Distribution  Date,  subject  to
adjustment in certain  events as specified in the  Agreement.  Distributions  in
reduction of the principal balance of certain Subclasses of Class A Certificates
may not commence on the first  Distribution Date specified above.  Distributions
of principal will be allocated  among the Subclasses of Class A Certificates  in
accordance with the provisions of the Agreement.  The  pass-through  rate on the
Class A-1 Certificates  applicable to each  Distribution Date will be 7.250% per
annum.  The amount of interest  which accrues on this  Certificate  in any month
will  be  subject  to  reduction  with  respect  to any  Non-Supported  Interest
Shortfall and the interest  portion of certain  Realized Losses allocated to the
Class A-1 Certificates, as described in the Agreement.

     Distributions  on this  Certificate  will be made on behalf of the  Trustee
either by the  Master  Servicer  or by a Paying  Agent  appointed  by the Master
Servicer by check mailed to the address of the Person entitled thereto,  as such
name and address shall appear on the Certificate Register, unless such Person is
entitled to receive payments by wire transfer in immediately  available funds in
accordance with the Pooling and Servicing Agreement and such Person has notified
the Master  Servicer  pursuant to the Pooling and Servicing  Agreement that such
payments  are to be  made by  wire  transfer  of  immediately  available  funds.

balance of this  Certificate  will be made after due notice of the  pendency  of

pursuant to a Pooling and Servicing Agreement dated as of November 26, 1997 (the
"Agreement") among the Seller, Norwest Bank Minnesota,  National Association, as
master  servicer (the "Master  Servicer"),  First Union  National Bank, as trust

the  Agreement.  This  Certificate  is issued under and is subject to the terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

     Pursuant to the terms of the Agreement,  a distribution will be made on the
25th day of each month or, if such 25th day is not a Business  Day, the Business
Day immediately  following (the  "Distribution  Date"),  commencing on the first
Distribution  Date specified above, to the Person in whose name this Certificate
is  registered  at the close of business on the last  Business  Day of the month
preceding the month of such  distribution,  in an amount equal to the product of

rate  of  interest  determined  as  provided  herein  and  as  specified  in the
Agreement.  Interest  on this  Certificate  will  accrue  with  respect  to each
Distribution  Date  during  the period  commencing  on the 25th day of the month

Thereafter,  with  respect to each LIBOR  Based  Interest  Accrual  Period,  the

     THIS CERTIFIES THAT  ___________________________ is the registered owner of
the Percentage  Interest evidenced by this Certificate in monthly  distributions
to the  Holders  of  Class  A-3  Certificates  with  respect  to a Trust  Estate
consisting of a pool of fixed  interest rate,  conventional,  monthly pay, fully
amortizing,  first lien, one- to four-family  residential  mortgage  loans,  and
which may  include  loans  secured  by  shares  issued  by  cooperative  housing
corporations  (the  "Mortgage  Loans"),   formed  by  Norwest  Asset  Securities
Corporation  (hereinafter called the "Seller", which term includes any successor
entity  under the  Agreement  referred to below).  The Trust  Estate was created
pursuant to a Pooling and Servicing Agreement dated as of November 26, 1997 (the
"Agreement") among the Seller, Norwest Bank Minnesota,  National Association, as
master  servicer (the "Master  Servicer"),  First Union  National Bank, as trust
administrator (the "Trust Administrator") and United States Trust Company of New
York,  as  trustee  (the  "Trustee"),  a summary  of  certain  of the  pertinent
provisions of which is set forth hereinafter.  To the extent not defined herein,
the  capitalized  terms used herein have the meanings  ascribed to such terms in
the  Agreement.  This  Certificate  is issued under and is subject to the terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

     Pursuant to the terms of the Agreement,  a distribution will be made on the
25th day of each month or, if such 25th day is not a Business  Day, the Business
Day immediately  following (the  "Distribution  Date"),  commencing on the first
Distribution  Date specified above, to the Person in whose name this Certificate
is  registered  at the close of business on the last  Business  Day of the month
preceding the month of such  distribution,  in an amount equal to the product of
the Percentage  Interest  evidenced by this Certificate and the Class A Subclass
Distribution Amount for the Class A-3 Certificates required to be distributed to
Holders  of  Class  A-3  Certificates  on such  Distribution  Date,  subject  to
adjustment  in  certain  events as  specified  in the  Agreement.  The Class A-3
Certificates  are not  entitled  to  receive  distributions  of  principal.  The
pass-through rate on the Class A-3 Certificates  applicable to each Distribution
Date will be a floating rate of interest  determined  as provided  herein and as
specified  in the  Agreement.  Interest  on this  Certificate  will  accrue with
respect to each  Distribution  Date during the period commencing on the 25th day
of the month  preceding  the month in which such  Distribution  Date  occurs and
ending on the 24th day of the month in which such Distribution Date occurs (each
a "LIBOR Based Interest Accrual Period").  The pass-through rate applicable with
respect to the initial LIBOR Based  Interest  Accrual Period will be 2.9125% per
annum. Thereafter, with respect to each LIBOR Based Interest Accrual Period, the
pass-through  rate will be a per  annum  rate  equal to 8.60%  minus  LIBOR,  as
determined on the second  business day preceding the  commencement of such LIBOR
Based Interest Accrual Period,  subject to a minimum rate of 0.00% and a maximum
rate of 8.60%.  The amount of interest which accrues on this  Certificate in any
month will be subject to reduction  with respect to any  Non-Supported  Interest
Shortfall and the interest  portion of certain  Realized Losses allocated to the
Class A-3 Certificates, as described in the Agreement.

     Distributions  on this  Certificate  will be made on behalf of the  Trustee
either by the  Master  Servicer  or by a Paying  Agent  appointed  by the Master
Servicer by check mailed to the address of the Person entitled thereto,  as such
name and address shall appear on the Certificate Register, unless such Person is
entitled to receive payments by wire transfer in immediately  available funds in
accordance with the Pooling and Servicing Agreement and such Person has notified
the Master  Servicer  pursuant to the Pooling and Servicing  Agreement that such
payments  are to be  made by  wire  transfer  of  immediately  available  funds.
Notwithstanding  the above,  the final  distribution on this Certificate will be
made  after  due  notice  of the  pendency  of such  distribution  and only upon
presentation and surrender of this Certificate at the office or agency specified
by the Trust Administrator for that purpose in the notice of final distribution.

     Reference is hereby made to the further  provisions of this Certificate set
forth on the reverse  hereof,  which further  provisions  shall for all purposes
have the same effect as if set forth at this place.

     This  Certificate  is issued on  November  26,  1997,  at an issue price of
4.88309% of the initial Class A-3 Notional Amount,  including  accrued interest,
and a stated  redemption  price at maturity equal to all interest  distributions
hereon,  and is issued with original issue  discount  ("OID") for federal income
tax  purposes.  Assuming  (a) that  this  Certificate  pays in  accordance  with
projected  cash  flows  reflecting  the  prepayment  assumption  of 240% SPA (as
defined in the Prospectus Supplement dated November 20, 1997 with respect to the
offering of the Class A-1,  Class A-2,  Class A-3,  Class A-4,  Class A-5, Class
A-6, Class A-7, Class A-8, Class A-9, Class A-R and Class A-LR Certificates, the
Class M Certificates and the Class B-1 and Class B-2 Certificates) used to price
this  Certificate  and (b) that the  interest  rate at  which  distributions  of
interest on this Certificate  actually will be made will be determined as though
the pass-through rate on this Certificate  applicable to the first  Distribution
Date will not change  thereafter:  (i) the amount of OID as a percentage  of the
initial Class A-3 Notional Amount is approximately 5.50539920%;  (ii) the annual
yield to maturity of this  Certificate,  compounded  monthly,  is  approximately
41.85%;  and (iii) the amount of OID allocable to the short first accrual period
(November  26, 1997 to December 25, 1997) as a percentage  of the initial  Class
A-3  Notional  Amount,  calculated  using the  exact  method,  is  approximately
0.16453742%.

     This  Certificate  constitutes  a  "regular  interest"  in a  "real  estate
mortgage  investment  conduit" as those terms are defined in Section  860G(a)(1)
and  Section  860D,  respectively,  of the  Internal  Revenue  Code of 1986,  as
amended.

     Unless this Certificate has been  countersigned by an authorized officer of
the Trust  Administrator,  by manual  signature,  this Certificate  shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

     THIS CERTIFIES THAT  ___________________________ is the registered owner of
the Percentage  Interest evidenced by this Certificate in monthly  distributions
to the  Holders of Class  A-WIO  Certificates  with  respect  to a Trust  Estate
consisting of a pool of fixed  interest rate,  conventional,  monthly pay, fully

which may  include  loans  secured  by  shares  issued  by  cooperative  housing
corporations  (the  "Mortgage  Loans"),   formed  by  Norwest  Asset  Securities
Corporation  (hereinafter called the "Seller", which term includes any successor
entity  under the  Agreement  referred to below).  The Trust  Estate was created

"Agreement") among the Seller, Norwest Bank Minnesota,  National Association, as
master  servicer (the "Master  Servicer"),  First Union  National Bank, as trust

provisions of which is set forth hereinafter.  To the extent not defined herein,
the  capitalized  terms used herein have the meanings  ascribed to such terms in
the  Agreement.  This  Certificate  is issued under and is subject to the terms,
provisions  and conditions of the  Agreement,  to which  Agreement the Holder of
this  Certificate by virtue of the  acceptance  hereof assents and by which such
Holder is bound.

     Pursuant to the terms of the Agreement,  a distribution will be made on the
25th day of each month or, if such 25th day is not a Business  Day, the Business
Day immediately  following (the  "Distribution  Date"),  commencing on the first
Distribution  Date specified above, to the Person in whose name this Certificate
is  registered  at the close of business on the last  Business  Day of the month
preceding the month of such  distribution,  in an amount equal to the product of
the Percentage  Interest  evidenced by this Certificate and the Class A Subclass
Distribution Amount for the Class A-WIO Certificates  required to be distributed
to Holders of Class A-WIO  Certificates on such  Distribution  Date,  subject to
adjustment  in certain  events as  specified in the  Agreement.  The Class A-WIO
Certificates  will not be entitled  to  distributions  in respect of  principal.
Interest  will  accrue on the Class A-WIO  Certificates  during each month in an
amount  equal to the  product  of (A)  1/12th of (i) the  Weighted  Average  Net
Mortgage  Interest Rate of the Premium  Mortgage  Loans on the first day of such
month  minus  (ii)  7.250%  and (B) the Class  A-WIO  Notional  Amount as of the
related  Distribution  Date.  The  amount  of  interest  which  accrues  on this
Certificate  in any month  will be  subject  to  reduction  with  respect to any
Non-Supported  Interest  Shortfall and the interest  portion of certain Realized

     Distributions  on this  Certificate  will be made on behalf of the  Trustee
either by the  Master  Servicer  or by a Paying  Agent  appointed  by the Master
Servicer by check mailed to the address of the Person entitled thereto,  as such
name and address shall appear on the Certificate Register, unless such Person is
entitled to receive payments by wire transfer in immediately  available funds in
accordance with the Pooling and Servicing Agreement and such Person has notified
the Master  Servicer  pursuant to the Pooling and Servicing  Agreement that such
payments  are to be  made by  wire  transfer  of  immediately  available  funds.
Notwithstanding  the above,  the final  distribution on this Certificate will be
made  after  due  notice  of the  pendency  of such  distribution  and only upon
presentation and surrender of this Certificate at the office or agency specified
by the Trust Administrator for that purpose in the notice of final distribution.

     No transfer of a Class A-WIO  Certificate will be made unless such transfer
is exempt from the  registration  requirements of the Securities Act of 1933, as
amended,  and any applicable state securities laws or is made in accordance with
said Act and laws.  In the event that such a  transfer  is desired to be made by
the Holder hereof,  (i) the transferee will be required to execute an investment
letter in the form described in the Agreement and (ii) if such transfer is to be
made within  three  years from the later of (a) the date of initial  issuance of
the  Certificates  or (b) the last  date on which the  Seller  or any  affiliate
thereof was a Holder of the Certificates proposed to be transferred,  and unless
such transfer is made in reliance on Rule 144A of the Securities Act of 1933, as
amended, the Trust Administrator or the Seller may require the Holder to deliver
an opinion of counsel  acceptable to and in form and substance  satisfactory  to
the Trust  Administrator and the Seller that such transfer is exempt (describing
the applicable  exemption and the basis therefor) from or is being made pursuant
to the registration  requirements of the Securities Act of 1933, as amended, and
of any  applicable  statute of any state.  The Holder hereof  desiring to effect
such transfer shall, and does hereby agree to, indemnify the Trustee,  the Trust
Administrator,  the Seller, the Master Servicer,  and any Paying Agent acting on
behalf of the Trust  Administrator  against any liability that may result if the
transfer  is not so exempt or is not made in  accordance  with such  Federal and
state laws. In connection with any such transfer,  the Trust  Administrator will
also  require  (i) a  representation  letter,  in the form as  described  in the
Agreement, stating that the transferee is not a Plan and is not acting on behalf
of a Plan or using the assets of a Plan to effect such  purchase or (ii) if such
transferee  is a Plan,  or is acting on behalf of or using the assets of a Plan,
(a) an opinion of counsel  acceptable to and in form and substance  satisfactory
to the Trust  Administrator  and the Seller with respect to certain  matters and
(b) such other  documentation  as the Seller or the Master Servicer may require,
as described in the Agreement.

     Reference is hereby made to the further  provisions of this Certificate set
forth on the reverse  hereof,  which further  provisions  shall for all purposes
have the same effect as if set forth at this place.

     This  Certificate  is issued on  November  26,  1997,  at an issue price of
1.66304% of the initial Class A-WIO Notional Amount, including accrued interest,
and a stated  redemption  price at maturity equal to all interest  distributions
hereon,  and is issued with original issue  discount  ("OID") for federal income
tax  purposes.  Assuming  (a) that  this  Certificate  pays in  accordance  with
projected  cash  flows  reflecting  the  prepayment  assumption  of 240% SPA (as
defined in the Prospectus Supplement dated November 20, 1997 with respect to the
offering of the Class A-1,  Class A-2,  Class A-3,  Class A-4,  Class A-5, Class
A-6, Class A-7, Class A-8, Class A-9, Class A-R and Class A-LR Certificates, the
Class M Certificates and the Class B-1 and Class B-2 Certificates) used to price
this  Certificate  and (b) that the  interest  rate at  which  distributions  of
interest on this Certificate  actually will be made will be determined as though
the pass-through rate on this Certificate  applicable to the first  Distribution
Date will not change  thereafter:  (i) the amount of OID as a percentage  of the
initial  Class A-WIO  Notional  Amount is  approximately  1.26491289%;  (ii) the
annual  yield  to  maturity  of  this  Certificate,   compounded   monthly,   is
approximately  13.10%;  and (iii) the amount of OID allocable to the short first
accrual  period  (November 26, 1997 to December 25, 1997) as a percentage of the
initial Class A-WIO  Notional  Amount,  calculated  using the exact  method,  is
approximately 0.01754446%.

     This  Certificate  constitutes  a  "regular  interest"  in a  "real  estate
mortgage  investment  conduit" as those terms are defined in Section  860G(a)(1)
and  Section  860D,  respectively,  of the  Internal  Revenue  Code of 1986,  as
amended.

amended, the Trust Administrator or the Seller may require the Holder to deliver
an opinion of counsel  acceptable to and in form and substance  satisfactory  to
the Trust  Administrator and the Seller that such transfer is exempt (describing

of any  applicable  statute of any state.  The Holder hereof  desiring to effect
such transfer shall, and does hereby agree to, indemnify the Trustee,  the Trust
Administrator,  the Seller, the Master Servicer,  and any Paying Agent acting on
behalf of the Trust  Administrator  against any liability that may result if the
transfer  is not so exempt or is not made in  accordance  with such  Federal and
state laws. In connection with any such transfer,  the Trust  Administrator will
also  require  (i) a  representation  letter,  in the form as  described  in the
Agreement,  stating  either  (a)  that the  transferee  is not a Plan and is not
acting on behalf of a Plan or using the assets of a Plan to effect such purchase
or (b) subject to certain conditions described in the Agreement, that the source
of funds used to purchase  this  Certificate  is an "insurance  company  general
account,"  or (ii) if such  transferee  is a Plan,  or is acting on behalf of or
using the assets of a Plan, (a) an opinion of counsel  acceptable to and in form
and  substance  satisfactory  to the Trust  Administrator  and the  Seller  with
respect to certain matters and (b) such other documentation as the Seller or the
Master Servicer may require, as described in the Agreement.

     Reference is hereby made to the further  provisions of this Certificate set
forth on the reverse  hereof,  which further  provisions  shall for all purposes

this Certificate: (i) the amount of OID as a percentage of the initial principal
balance of this Certificate is approximately 29.00066667%; (ii) the annual yield
to maturity of this Certificate,  compounded monthly,  is approximately  12.29%;
and (iii)  the  amount  of OID  allocable  to the  short  first  accrual  period

                [Form of Reverse of Series 1997-19 Certificates]

                      NORWEST ASSET SECURITIES CORPORATION
                       MORTGAGE PASS-THROUGH CERTIFICATES
                                 SERIES 1997-19

     This Certificate is one of a duly authorized  issue of Certificates  issued
in  several   Classes  and  Subclasses   designated  as  Mortgage   Pass-Through
Certificates  of the Series  specified  hereon (herein  collectively  called the
"Certificates").

     The Certificates are limited in right of payment to certain collections and
recoveries  respecting the Mortgage Loans,  all as more  specifically  set forth
herein and in the Agreement. In the event funds are advanced with respect to any
Mortgage  Loan by a Servicer,  the Master  Servicer or the Trust  Administrator,
such advances are  reimbursable  to such  Servicer,  the Master  Servicer or the
Trust  Administrator  to the extent  provided  in the  Agreement,  from  related
recoveries  on such  Mortgage  Loan or from  other  cash  that  would  have been
distributable to Certificateholders.

     As provided in the  Agreement,  withdrawals  from the  Certificate  Account
created for the benefit of Certificateholders may be made by the Master Servicer
from time to time for purposes other than  distributions to  Certificateholders,
such purposes including  reimbursement to a Servicer, the Master Servicer or the
Trust  Administrator,  as  applicable,  of advances made by such  Servicer,  the
Master Servicer or the Trust Administrator.

     The  Agreement  permits,  with certain  exceptions  therein  provided,  the
amendment of the Agreement and the modification of the rights and obligations of
the Seller, the Master Servicer,  the Trust  Administrator,  and the Trustee and
the  rights of the  Certificateholders  under the  Agreement  at any time by the
Seller,  the Master Servicer,  the Trust  Administrator and the Trustee with the
consent of the Holders of Certificates evidencing in the aggregate not less than
66 2/3% of the  Voting  Interests  of each  Class or  Subclass  of  Certificates
affected  thereby.  Any such consent by the Holder of this Certificate  shall be
conclusive  and  binding  on such  Holder  and upon all  future  holders of this
Certificate  and of any  Certificate  issued  upon  the  transfer  hereof  or in
exchange  hereof or in lieu hereof  whether or not  notation of such  consent is
made upon the Certificate.  The Agreement also permits the amendment  thereof in
certain  circumstances  without  the  consent  of  the  Holders  of  any  of the
Certificates.

     As provided in the Agreement and subject to certain limitations therein set
forth,  the  transfer of this  Certificate  is  registrable  in the  Certificate
Register upon surrender of this  Certificate for registration of transfer at the
office or agency  appointed  by the Trust  Administrator,  duly  endorsed by, or
accompanied  by an assignment  in the form below or other written  instrument of
transfer in form  satisfactory  to the Trust  Administrator  and the Certificate
Registrar,  duly executed by the Holder  hereof or such  Holder's  attorney duly
authorized in writing,  and thereupon one or more new Certificates of authorized
Denominations  evidencing  the same Class and Subclass and aggregate  Percentage
Interest will be issued to the designated transferee or transferees.

     The  Certificates  are issuable  only as  registered  Certificates  without
coupons in Classes and Denominations  specified in the Agreement. As provided in
the Agreement and subject to certain limitations therein set forth, Certificates
are exchangeable for new Certificates of authorized Denominations evidencing the
same Class and Subclass and aggregate Percentage  Interest,  as requested by the
Holder surrendering the same.

     No service  charge  will be made for any such  registration  of transfer or
exchange,  but the Trust Administrator or the Certificate  Registrar may require
payment  of a sum  sufficient  to  cover  any tax or other  governmental  charge
payable in connection therewith.

     The Seller, the Master Servicer,  the Trust Administrator,  the Trustee and
the Certificate Registrar, and any agent of the Seller, the Master Servicer, the
Trust  Administrator,  the Trustee or the Certificate  Registrar,  may treat the
Person in whose name this  Certificate is registered as the owner hereof for all
purposes,  and neither the Seller, the Master Servicer, the Trust Administrator,
the Trustee,  the Certificate  Registrar nor any such agent shall be affected by
notice to the contrary.

     The obligations created by the Agreement in respect of the Certificates and
the Trust Estate created  thereby shall  terminate upon the last action required
to be taken by the Trust  Administrator on the Final  Distribution Date pursuant
to the Agreement  following the earlier of (i) the payment or other  liquidation
(or advance with respect  thereto) of the last Mortgage Loan subject  thereto or
the  disposition  of all property  acquired upon  foreclosure or deed in lieu of
foreclosure  of any Mortgage  Loan, and (ii) the purchase by the Seller from the
Trust  Estate of all  remaining  Mortgage  Loans and all  property  acquired  in
respect of such Mortgage Loans; provided, however, that the Trust Estate will in
no event  continue  beyond the expiration of 21 years from the death of the last
survivor of the  descendants  of Joseph P. Kennedy,  the late  ambassador of the
United  States to the Court of St. James,  living on the date of the  Agreement.
The  Agreement  permits,  but does not  require,  the  Seller  to  purchase  all
remaining  Mortgage  Loans and all property  acquired in respect of any Mortgage
Loan at a price  determined as provided in the  Agreement.  The exercise of such
option will effect early retirement of the  Certificates,  the Seller's right to
exercise such option being subject to the Pool  Scheduled  Principal  Balance of
the Mortgage Loans as of the  Distribution  Date upon which the proceeds of such
repurchase  are  distributed  being less than ten  percent of the  Cut-Off  Date
Aggregate Principal Balance.

     THIS CUSTODIAL  AGREEMENT (as amended and  supplemented  from time to time,
the "Agreement"),  dated as of _____________,  by and among FIRST UNION NATIONAL
BANK,  not  individually,  but  solely  as Trust  Administrator  (including  its

                           W I T N E S S E T H   T H A T

     WHEREAS,  the Seller,  the Master  Servicer,  the Trust  Administrator  and
United States Trust Company of New York, as trustee, have entered into a Pooling
and Servicing  Agreement  dated as of November 26, 1997 relating to the issuance
of Mortgage Pass-Through Certificates,  Series 1997-19 (as in effect on the date
of this  Agreement,  the  "Original  Pooling and  Servicing  Agreement",  and as
amended  and  supplemented  from  time  to  time,  the  "Pooling  and  Servicing
Agreement"); and

     WHEREAS,   the  Custodian  has  agreed  to  act  as  agent  for  the  Trust
Administrator  for the purposes of receiving and holding  certain  documents and
other  instruments  delivered  by the Seller  under the  Pooling  and  Servicing
Agreement,  all upon the terms and  conditions  and  subject to the  limitations
hereinafter set forth;

     NOW,  THEREFORE,  in consideration of the premises and the mutual covenants
and agreements  hereinafter set forth, the Trust Administrator,  the Seller, the
Master Servicer and the Custodian hereby agree as follows:

                                    ARTICLE I

                                   Definitions

     Capitalized  terms used in this Agreement and not defined herein shall have
the meanings  assigned in the Original Pooling and Servicing  Agreement,  unless
otherwise required by the context herein.

                                   ARTICLE II

                          Custody of Mortgage Documents

     Section 2.1. Custodian to Act as Agent;  Acceptance of Custodial Files. The
Custodian,  as the duly  appointed  agent of the Trust  Administrator  for these
purposes,  acknowledges  receipt  of the  Mortgage  Notes,  the  Mortgages,  the
assignments and other documents relating to the Mortgage Loans identified on the
schedule  attached hereto and declares that it holds and will hold such Mortgage
Notes,  Mortgages,  assignments  and other  documents and any similar  documents
received  by  the  Trust  Administrator  subsequent  to  the  date  hereof  (the
"Custodial Files") as agent for the Trust  Administrator,  in trust, for the use
and benefit of all present and future Certificateholders.

     Section 2.2. Recordation of Assignments. If any Custodial File includes one
or more  assignments  to the Trust  Administrator  of Mortgage Notes and related
Mortgages that have not been recorded,  each such assignment  shall be delivered
by  the  Custodian  to  the  Seller  for  the  purpose  of  recording  it in the
appropriate  public  office for real  property  records,  and the Seller,  at no
expense to the Custodian, shall promptly cause to be recorded in the appropriate
public office for real property  records each such  assignment and, upon receipt
thereof  from such  public  office,  shall  return each such  assignment  to the
Custodian.

     Section 2.3.  Review of Custodial  Files.  The  Custodian  agrees,  for the
benefit of  Certificateholders,  to review, in accordance with the provisions of
Section 2.01 of the Pooling and Servicing Agreement,  each Custodial File. If in
performing  the review  required  by this  Section 2.3 the  Custodian  finds any
document or documents  constituting  a part of a Custodial File to be missing or
defective in any material  respect,  the Custodian  shall promptly so notify the
Seller, the Master Servicer and the Trust Administrator.

     Section 2.4.  Notification of Breaches of  Representations  and Warranties.
Upon  discovery by the Custodian of a breach of any  representation  or warranty
made by the  Seller  or the  Master  Servicer  as set forth in the  Pooling  and
Servicing  Agreement,  the  Custodian  shall give prompt  written  notice to the
Seller, the Master Servicer and the Trust Administrator.

     Section 2.5.  Custodian to Cooperate;  Release of Custodial Files. Upon the
payment in full of any Mortgage Loan, or the receipt by the Master Servicer of a
notification  that  payment in full will be escrowed in a manner  customary  for
such purposes,  the Master Servicer shall immediately  notify the Custodian by a
certification  (which certification shall include a statement to the effect that
all amounts received or to be received in connection with such payment which are
required to be deposited in the Certificate  Account pursuant to Section 3.02 of
the Pooling and  Servicing  Agreement  have been or will be so  deposited)  of a
Servicing  Officer and shall request  delivery to it of the Custodial  File. The
Custodian agrees,  upon receipt of such  certification and request,  promptly to
release the related Custodial File to the Master Servicer.

     From time to time as is appropriate for the servicing or foreclosure of any
Mortgage Loan, the Master  Servicer shall deliver to the Custodian a certificate
of a Servicing  Officer  requesting  that  possession  of all,  or any  document
constituting  part of, the Custodial File be released to the Master Servicer and
certifying  as to the reason for such  release  and that such  release  will not
invalidate any insurance coverage provided in respect of the Mortgage Loan. With
such  certificate,  the Master Servicer shall deliver to the Custodian a receipt
signed by a Servicing Officer on behalf of the Master Servicer, and upon receipt
of the  foregoing,  the  Custodian  shall  deliver  the  Custodial  File or such
document to the Master Servicer.  The Master Servicer shall cause each Custodial
File or any document  therein so released to be returned to the  Custodian  when
the need  therefor  by the  Master  Servicer  no longer  exists,  unless (i) the
Mortgage Loan has been liquidated and the Liquidation  Proceeds  relating to the
Mortgage  Loan have been  deposited  in the  Certificate  Account  to the extent
required by the Pooling and Servicing  Agreement or (ii) the  Custodial  File or
such document has been delivered to an attorney, or to a public trustee or other
public official as required by law, for purposes of initiating or pursuing legal
action or other proceedings for the foreclosure of the Mortgaged Property either
judicially  or  non-judicially,  and the Master  Servicer  has  delivered to the
Custodian a  certificate  of a Servicing  Officer  certifying as to the name and
address  of the  Person  to which  such  Custodial  File or such  document  were
delivered  and the  purpose or purposes  of such  delivery.  In the event of the
liquidation of a Mortgage  Loan,  the Custodian  shall deliver such receipt with
respect thereto to the Master  Servicer upon deposit of the related  Liquidation
Proceeds in the  Certificate  Account to the extent  required by the Pooling and
Servicing Agreement.

     Section  2.6.  Assumption  Agreements.  In the  event  that any  assumption
agreement or substitution of liability agreement is entered into with respect to
any Mortgage  Loan subject to this  Agreement in  accordance  with the terms and
provisions of the Pooling and Servicing  Agreement,  the Master  Servicer  shall
notify the Custodian  that such  assumption or  substitution  agreement has been
completed by  forwarding  to the  Custodian  the original of such  assumption or
substitution agreement,  which copy shall be added to the related Custodial File
and, for all purposes,  shall be considered a part of such Custodial File to the
same extent as all other documents and instruments constituting parts thereof.

                                   ARTICLE III

                            Concerning the Custodian

     Section 3.1. Custodian a Bailee and Agent of the Trust Administrator.  With
respect to each Mortgage Note,  Mortgage and other documents  constituting  each
Custodian  File  which  are  delivered  to  the  Custodian,   the  Custodian  is
exclusively  the  bailee  and  agent  of the  Trust  Administrator,  holds  such
documents for the benefit of  Certificateholders  and undertakes to perform such
duties and only such  duties as are  specifically  set forth in this  Agreement.
Except upon compliance with the provisions of Section 2.5 of this Agreement,  no
Mortgage  Note,  Mortgage or other  document  constituting a part of a Custodial
File shall be delivered by the Custodian to the Seller or the Master Servicer or
otherwise released from the possession of the Custodian.

     Section 3.2.  Indemnification.  The Seller  hereby  agrees to indemnify and
hold the Custodian  harmless from and against all claims,  liabilities,  losses,
actions,  suits or proceedings at law or in equity, or any other expenses,  fees
or charges of any  character or nature,  which the  Custodian  may incur or with
which the  Custodian  may be  threatened  by reasons of its acting as  custodian
under this Agreement, including indemnification of the Custodian against any and
all expenses,  including  attorney's  fees if counsel for the Custodian has been
approved  by the  Seller,  and  the  cost  of  defending  any  action,  suit  or
proceedings  or  resisting  any  claim.  Notwithstanding  the  foregoing,  it is
specifically  understood and agreed that in the event any such claim, liability,
loss,  action,  suit or proceeding or other expense,  fees, or charge shall have
been caused by reason of any negligent act, negligent failure to act, or willful
misconduct  on the part of the  Custodian,  or which shall  constitute a willful
breach of its duties hereunder, the indemnification provisions of this Agreement
shall not apply.

     Section  3.3.  Custodian  May  Own  Certificates.   The  Custodian  in  its
individual or any other capacity may become the owner or pledgee of Certificates
with the same rights it would have if it were not Custodian.

     Section 3.4.  Master  Servicer to Pay  Custodian's  Fees and Expenses.  The
Master Servicer  covenants and agrees to pay to the Custodian from time to time,
and the Custodian shall be entitled to, reasonable compensation for all services
rendered by it in the exercise and  performance  of any of the powers and duties
hereunder of the  Custodian,  and the Master  Servicer will pay or reimburse the
Custodian  upon its  request  for all  reasonable  expenses,  disbursements  and
advances  incurred  or made  by the  Custodian  in  accordance  with  any of the
provisions of this  Agreement  (including the  reasonable  compensation  and the
expenses and  disbursements  of its counsel and of all persons not  regularly in
its employ), except any such expense,  disbursement or advance as may arise from
its negligence or bad faith.

     Section  3.5.  Custodian  May  Resign;   Trust   Administrator  May  Remove
Custodian.  The  Custodian  may resign from the  obligations  and duties  hereby
imposed upon it as such obligations and duties relate to its acting as Custodian
of the Mortgage  Loans.  Upon  receiving such notice of  resignation,  the Trust
Administrator  shall either take custody of the Custodial  Files itself and give
prompt notice  thereof to the Seller,  the Master  Servicer and the Custodian or
promptly appoint a successor Custodian by written instrument,  in duplicate, one
copy of which instrument  shall be delivered to the resigning  Custodian and one
copy to the successor Custodian. If the Trust Administrator shall not have taken
custody of the  Custodial  Files and no successor  Custodian  shall have been so
appointed and have accepted  resignation,  the resigning  Custodian may petition
any  court  of  competent  jurisdiction  for  the  appointment  of  a  successor
Custodian.

     The Trust  Administrator  may remove  the  Custodian  at any time.  In such
event, the Trust  Administrator  shall appoint, or petition a court of competent
jurisdiction  to  appoint,  a  successor  Custodian  hereunder.   Any  successor
Custodian  shall  be  a  depository   institution   subject  to  supervision  or
examination by federal or state authority and shall be able to satisfy the other
requirements contained in Section 3.7.

     Any  resignation or removal of the Custodian and appointment of a successor
Custodian  pursuant to any of the  provisions  of this  Section 3.5 shall become
effective upon acceptance of appointment by the successor  Custodian.  The Trust
Administrator  shall give prompt notice to the Seller and the Master Servicer of
the appointment of any successor  Custodian.  No successor  Custodian shall have
been appointed and accepted  appointment by the Trust Administrator  without the
prior approval of the Seller and the Master Servicer.

     Section 3.6. Merger or  Consolidation  of Custodian.  Any Person into which
the Custodian  may be merged or converted or with which it may be  consolidated,
or any Person  resulting from any merger,  conversion or  consolidation to which
the Custodian shall be a party, or any Person  succeeding to the business of the
Custodian,  shall be the  successor  of the  Custodian  hereunder,  without  the
execution  or filing of any paper or any  further  act on the part of any of the
parties hereto, anything herein to the contrary notwithstanding.

     Section  3.7.  Representations  of  the  Custodian.  The  Custodian  hereby
represents  that  it is a  depository  institution  subject  to  supervision  or
examination by a federal or state authority,  has a combined capital and surplus
of at least  $10,000,000 and is qualified to do business in the  jurisdiction in
which it will hold any Custodian File.

                                   ARTICLE IV

particular  party whose address is stated herein by similar  notice in writing),
in which case the notice will be deemed delivered when received.

     Section 4.2.  Amendments.  No modification or amendment of or supplement to
this  Agreement  shall be valid or  effective  unless the same is in writing and
signed by all parties  hereto,  and neither the Seller,  the Master Servicer nor
the  Trust  Administrator  shall  enter  into any  amendment  hereof  except  as
permitted by the Pooling and Servicing Agreement.  The Trust Administrator shall
give prompt  notice to the  Custodian  of any  amendment  or  supplement  to the
Pooling and Servicing  Agreement and furnish the Custodian  with written  copies
thereof.

     Section 4.3.  Governing Law. This Agreement shall be deemed a contract made
under the laws of the State of New York and shall be  construed  and enforced in

applicable  law, this  Agreement is subject to  recordation  in all  appropriate
public offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the properties subject to the Mortgages are

direction by the Trust Administrator,  but only upon direction accompanied by an
Opinion  of  Counsel  to  the  effect  that  such  recordation   materially  and
beneficially affects the interests of the Certificateholders.

     For the purpose of facilitating the recordation of this Agreement as herein
provided and for other purposes,  this Agreement may be executed  simultaneously

covenants,  agreements,  provisions or terms of this Agreement  shall be for any
reason whatsoever held invalid, then such covenants,  agreements,  provisions or
terms  shall be  deemed  severable  from the  remaining  covenants,  agreements,
provisions or terms of this Agreement and shall in no way affect the validity or
enforceability  of the other provisions of this Agreement or of the Certificates
or the rights of the holders thereof.

     Section 2.  Representations and Warranties of the Purchaser.  In connection
with the proposed transfer, the Purchaser represents and warrants to NASCOR, the

     (a) The Purchaser is duly organized,  validly existing and in good standing
under the laws of the  jurisdiction  in which the  Purchaser  is  organized,  is
authorized to invest in the Class [A-WIO] [A-PO] [B-3] [B-4] [B-5] Certificates,
and to  enter  into  this  Agreement,  and  duly  executed  and  delivered  this
Agreement.

     (b) The Purchaser is acquiring  the Class [A-WIO]  [A-PO] [B-3] [B-4] [B-5]

     [(c) The Purchaser  has knowledge of financial and business  matters and is
capable of evaluating the merits and risks of an investment in the Class [A-WIO]
[A-PO] [B-3] [B-4] [B-5] Certificates; the Purchaser has sought such accounting,
legal  and tax  advice  as it has  considered  necessary  to  make  an  informed
investment  decision;  and the Purchaser is able to bear the economic risk of an
investment in the Class [A-WIO]  [A-PO] [B-3] [B-4] [B-5]  Certificates  and can
afford a complete loss of such investment.]

     [(c) The Purchaser is a "Qualified  Institutional Buyer" within the meaning
of Rule 144A of the Act.]

     (d) The Purchaser  confirms that (a) it has received and reviewed a copy of
the Private Placement Memorandum dated _____________,  _______,  relating to the
Class [A-WIO] [A-PO] [B-3] [B-4] [B-5] Certificates and reviewed,  to the extent
it deemed  appropriate,  the  documents  attached  thereto  or  incorporated  by
reference  therein,  (b) it has had the  opportunity  to ask  questions  of, and
receive  answers from NASCOR  concerning  the Class  [A-WIO]  [A-PO] [B-3] [B-4]
[B-5]  Certificates and all matters relating thereto,  and obtain any additional
information (including documents) relevant to its decision to purchase the Class
[A-WIO]  [A-PO]  [B-3] [B-4] [B-5]  Certificates  that NASCOR  possesses  or can
possess without unreasonable effort or expense and (c) it has undertaken its own
independent  analysis of the  investment in the Class [A-WIO] [A-PO] [B-3] [B-4]
[B-5]  Certificates.  The Purchaser will not use or disclose any  information it
receives in connection with its purchase of the Class [A-WIO] [A-PO] [B-3] [B-4]
[B-5]  Certificates  other than in  connection  with a subsequent  sale of Class
[A-WIO] [A-PO] [B-3] [B-4] [B-5] Certificates.

retirement  arrangement  subject to Title I of the  Employee  Retirement  Income
Security  Act of 1974,  as amended,  ("ERISA"),  or Section 4975 of the Internal
Revenue Code of 1986,  as amended  (the  "Code"),  or a  governmental  plan,  as
defined in Section  3(32) of ERISA,  subject to any federal,  state or local law
("Similar  Law")  which is,  to a  material  extent,  similar  to the  foregoing
provisions  of ERISA or the Code  (collectively,  a "Plan"),  an agent acting on
behalf of a Plan, or a person  utilizing the assets of a Plan or (ii) [for Class
[B-3][B-4][B-5] Certificates only] if the Purchaser is an insurance company, the
source of funds used to purchase  the Class  [B-3][B-4][B-5]  Certificate  is an
"insurance  company general account" (as such term is defined in Section V(e) of
Prohibited  Transaction Class Exemption 95-60 ("PTE 95-60"),  60 Fed. Reg. 35925
(July 12,  1995) and there is no Plan with  respect  to which the amount of such
general  account's  reserves and liabilities  for the contract(s)  held by or on
behalf of such Plan and all other  Plans  maintained  by the same  employer  (or
affiliate  thereof as  defined  in Section  V(a)(1) of PTE 95-60) or by the same
employee  organization  exceeds 10% of the total of all reserves and liabilities
of such general  account (as such amounts are  determined  under Section I(a) of

"Benefit Plan Opinion" satisfactory to NASCOR and the Trust Administrator of the
Trust Estate and (b) such other opinions of counsel,  officers' certificates and
agreements as NASCOR or the Master  Servicer may have  required.  A Benefit Plan
Opinion is an opinion of counsel to the effect that the proposed  transfer  will
not cause the assets of the Trust  Estate to be  regarded  as "plan  assets" and
subject to the prohibited  transaction  provisions of ERISA, the Code or Similar
Law and will not subject the Trust Administrator, the Trustee, the Seller or the
Master Servicer to any obligation in addition to those undertaken in the Pooling
and Servicing  Agreement  (including any liability for civil penalties or excise
taxes imposed pursuant to ERISA, Section 4975 of the Code or Similar Law).

     (f)  If  the  Purchaser  is  a  depository   institution   subject  to  the
jurisdiction of the Office of the Comptroller of the Currency ("OCC"), the Board
of  Governors  of the  Federal  Reserve  System  ("FRB"),  the  Federal  Deposit
Insurance Corporation ("FDIC"),  the Office of Thrift Supervision ("OTS") or the
National Credit Union  Administration  ("NCUA"),  the Purchaser has reviewed the
"Supervisory  Policy Statement on Securities  Activities" dated January 28, 1992
of the Federal Financial Institutions Examination Council and the April 15, 1994
Interim  Revision  thereto as adopted by the OCC, FRB,  FDIC, OTS and NCUA (with
modifications  as  applicable),  as  appropriate,  other  applicable  investment
authority,  rules, supervisory policies and guidelines of these agencies and, to
the extent  appropriate,  state banking  authorities  and has concluded that its
purchase  of the Class  [A-WIO]  [A-PO]  [B-3] [B-4]  [B-5]  Certificates  is in
compliance therewith.

     Section 3. Transfer of Class [A-WIO] [A-PO] [B-3] [B-4] [B-5] Certificates.

     (a) The Purchaser  understands  that the Class  [A-WIO]  [A-PO] [B-3] [B-4]
[B-5]  Certificates  have not been  registered  under the Securities Act of 1933
(the "Act") or any state securities laws and that no transfer may be made unless
the Class [A-WIO] [A-PO] [B-3] [B-4] [B-5] Certificates are registered under the
Act and  applicable  state law or  unless  an  exemption  from  registration  is
available.  The Purchaser  further  understands that neither NASCOR,  the Master
Servicer nor the Trust  Administrator  is under any  obligation  to register the
Class  [A-WIO]  [A-PO]  [B-3]  [B-4]  [B-5]  Certificates  or make an  exemption
available.  In the event that such a transfer is to be made in reliance  upon an
exemption  from the Act or  applicable  state  securities  laws,  (i) the  Trust
Administrator  shall require, in order to assure compliance with such laws, that
the  Certificateholder's  prospective transferee certify to NASCOR and the Trust
Administrator  as to the factual  basis for the  registration  or  qualification
exemption   relied  upon,  and  (ii)  unless  the  transferee  is  a  "Qualified
Institutional  Buyer"  within  the  meaning  of Rule 144A of the Act,  the Trust
Administrator  or NASCOR may, if such  transfer is made within  three years from
the later of (a) the  Closing  Date or (b) the last date on which  NASCOR or any
affiliate  thereof was a holder of the Certificates  proposed to be transferred,
require an Opinion of Counsel  that such  transfer  may be made  pursuant  to an
exemption from the Act and state securities laws, which Opinion of Counsel shall
not be an expense of the Trust Administrator, the Master Servicer or NASCOR. Any
such  Certificateholder  desiring to effect such transfer shall, and does hereby
agree to, indemnify the Trustee, the Trust  Administrator,  the Master Servicer,
any Paying Agent acting on behalf of the Trust  Administrator and NASCOR against
any liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

     (b) No transfer of a Class  [A-WIO]  [A-PO]  [B-3] [B-4] [B-5]  Certificate
shall be made unless the transferee  provides NASCOR and the Trust Administrator
with a Transferee's Letter, substantially in the form of this Agreement.

     (c) The Purchaser  acknowledges  that its Class [A-WIO]  [A-PO] [B-3] [B-4]
[B-5]  Certificates  bear a legend setting forth the applicable  restrictions on
transfer.

     Section 2.01 Reports and Notices

     (a) In connection  with the performance of its duties under the Pooling and
Servicing  Agreement  relating to the realization upon defaulted Mortgage Loans,
the Company as Master  Servicer  shall  provide to the  Purchaser  the following
notices and reports:

          (i)  Within  five  Business  Days  after  each  Distribution  Date (or
     included in or with the monthly statements to  Certificateholders  pursuant
     to the Pooling and Servicing Agreement),  the Company, shall provide to the
     Purchaser a report,  using the same  methodology  and  calculations  in its
     standard servicing  reports,  indicating for the Trust Estate the number of
     Mortgage Loans that are (A) thirty days, (B) sixty days, (C) ninety days or
     more  delinquent  or (D) in  foreclosure,  and  indicating  for  each  such
     Mortgage Loan the loan number and outstanding principal balance.

          (ii) Prior to the  Commencement  of Foreclosure in connection with any
     Mortgage  Loan,  the Company shall cause (to the extent that the Company as
     Master  Servicer  is  granted  such  authority  in  the  related  Servicing
     Agreement)  the  Servicer to provide the  Purchaser  with a notice (sent by
     telecopier)  of such  proposed and imminent  foreclosure,  stating the loan
     number and the aggregate  amount owing under the Mortgage Loan. Such notice
     may be provided to the Purchaser in the form of a copy of a referral letter
     from  such  Servicer  to  an  attorney   requesting   the   institution  of
     foreclosure.

     (b) If requested by the Purchaser, the Company shall cause the Servicer (to
the extent that the Company as Master  Servicer is granted such authority in the
related Servicing  Agreement) to make its servicing  personnel available (during
their normal business hours) to respond to reasonable inquiries,  by phone or in
writing  by  facsimile,  electronic,  or  overnight  mail  transmission,  by the
Purchaser in  connection  with any Mortgage  Loan  identified  in a report under
subsection  (a) (i) (B),  (a) (i) (C),  (a) (i) (D),  or (a) (ii) which has been
given to the Purchaser;  provided,  that (1) the related  Servicer shall only be
required to provide  information  that is readily  accessible  to its  servicing
personnel and is  non-confidential  and (2) the related  Servicer  shall respond
within five Business Days orally or in writing by facsimile transmission.

     (c) In addition to the foregoing,  the Company shall cause the Servicer (to
the extent that the Company as Master  Servicer is granted such authority in the
related Servicing Agreement) to provide to the Purchaser such information as the
Purchaser may reasonably  request  provided,  however,  that such information is
consistent with normal reporting  practices,  concerning each Mortgage Loan that
is at least ninety days  delinquent and each Mortgage Loan which has become real
estate owned, through the final liquidation thereof;  provided, that the related
Servicer  shall  only  be  required  to  provide  information  that  is  readily
accessible to its servicing personnel and is non-confidential provided, however,
that the Purchaser will  reimburse the Company and the related  Servicer for any
out of pocket expenses.

     Section 2.02 Purchaser's Election to Delay Foreclosure Proceedings

     (a) The  Purchaser  shall be deemed to direct the Company to direct (to the
extent that the  Company as Master  Servicer is granted  such  authority  in the
related  Servicing  Agreement)  the related  Servicer that in the event that the
Company does not receive written notice of the Purchaser's  election pursuant to
subsection (b) below within 24 hours (exclusive of any intervening  non-Business
Days) of  transmission  of the notice provided by the Company under Section 2.01
(a) (ii)  subject to  extension  as set forth in Section  2.02(b),  the  related
Servicer may proceed with the  Commencement  of  Foreclosure  in respect of such
Mortgage Loan in accordance with its normal foreclosure policies without further
notice  to the  Purchaser.  Any  foreclosure  that  has  been  initiated  may be
discontinued  (i) without  notice to the Purchaser if the Mortgage Loan has been
brought  current or if a refinancing  or  prepayment  occurs with respect to the
Mortgage  Loan  (including  by means of a short  payoff  approved by the related
Servicer) or (ii) if the related Servicer has reached the terms of a forbearance
agreement  with the  borrower.  In the latter  case,  the related  Servicer  may
complete such forbearance agreement unless instructed otherwise by the Purchaser
within two Business Days notification.

     (b) In  connection  with any  Mortgage  Loan with respect to which a notice
under Section  2.01(a)(ii)  has been given to the  Purchaser,  the Purchaser may
elect to instruct the Company to cause, to the extent that the Company as Master
Servicer is granted  such  authority  in the related  Servicing  Agreement,  the
related Servicer to delay the Commencement of Foreclosure until such time as the
Purchaser determines that the related Servicer may proceed with the Commencement
of  Foreclosure.  Such  election  must be evidenced by written  notice  received
within 24 hours (exclusive of any intervening non-Business Days) of transmission
of the notice  provided by the Company under Section  2.01(a)(ii).  Such 24 hour
period shall be extended for no longer than an  additional  four  Business  Days
after the  receipt  of the  information  if the  Purchaser  requests  additional
information related to such foreclosure;  provided,  however, that the Purchaser
will have at least one  Business  Day to  respond  to any  requested  additional
information.  Any such  additional  information  shall be  provided  only to the
extent  it (i) is not  confidential  in  nature  and (ii) is  obtainable  by the
related  Servicer  from  existing  reports,  certificates  or  statements  or is
otherwise readily  accessible to its servicing  personnel.  The Purchaser agrees
that it has no right to deal with the mortgagor during such period.  However, if
such servicing activities include acceptance of a deed-in-lieu of foreclosure or
short  payoff,  the  Purchaser  will be notified and given two Business  Days to
respond.

     (c) With respect to any Mortgage Loan as to which the Purchaser has made an
Election to Delay Foreclosure, the Purchaser shall obtain a Current Appraisal as
soon as practicable,  but in no event more than 15 business days thereafter, and
shall provide the Company with a copy of such Current Appraisal.

     (d) Within two Business  Days of making any Election to Delay  Foreclosure,
the Purchaser  shall remit by wire  transfer to the Company,  for deposit in the
Collateral  Fund, an amount,  as calculated by the Company,  equal to the sum of
(i) 125% of the greater of the unpaid principal balance of the Mortgage Loan and
the value shown in the Current  Appraisal  referred to in  subsection  (c) above
(or, if such Current Appraisal has not yet been obtained, the Company's estimate
thereof,  in which case the  required  deposit  under this  subsection  shall be
adjusted upon obtaining such Current Appraisal), and (ii) three months' interest
on the Mortgage Loan at the applicable  Mortgage  Interest Rate. If any Election
to Delay Foreclosure extends for a period in excess of three months (such excess
period  being  referred to herein as the "Excess  Period"),  within two Business
Days the  Purchaser  shall remit by wire  transfer in advance to the Company for
deposit in the Collateral Fund the amount of each additional  month's  interest,
as  calculated  by the Company,  equal to interest on the  Mortgage  Loan at the
applicable  Mortgage  Interest  Rate for the  Excess  Period.  The terms of this
Agreement  will no longer apply to the  servicing of any Mortgage  Loan upon the
failure of the  Purchaser  to deposit any of the above  amounts  relating to the
Mortgage Loan within two Business Days of the Election to Delay  Foreclosure  or
within two Business Days of the  commencement  of the Excess  Period  subject to
Section 3.01.

     (e) With respect to any Mortgage Loan as to which the Purchaser has made an
Election to Delay Foreclosure, the Company may withdraw from the Collateral Fund
from time to time amounts  necessary to reimburse  the related  Servicer for all
related  Monthly  Advances  and  Liquidation  Expenses  thereafter  made by such
Servicer in accordance with the Pooling and Servicing  Agreement and the related
Servicing  Agreement.  To the  extent  that the  amount of any such  Liquidation
Expenses is determined by the Company based on estimated  costs,  and the actual
costs are  subsequently  determined  to be higher,  the Company may withdraw the
additional  amount from the Collateral Fund. In the event that the Mortgage Loan
is brought current by the mortgagor and the foreclosure  action is discontinued,
the amounts so withdrawn from the Collateral Fund shall be redeposited if and to
the extent that reimbursement therefor from amounts paid by the mortgagor is not
prohibited  pursuant  to the  Pooling  and  Servicing  Agreement  or the related
Servicing  Agreement,  applicable law or the related  mortgage  note.  Except as
provided in the preceding  sentence,  amounts withdrawn from the Collateral Fund
to cover Monthly  Advances and  Liquidation  Expenses  shall not be  redeposited
therein or otherwise reimbursed to the Purchaser.  If and when any such Mortgage
Loan  is  brought  current  by  the  mortgagor,  all  amounts  remaining  in the
Collateral  Fund in respect of such  Mortgage  Loan  (after  adjustment  for all
permitted  withdrawals  and  deposits  pursuant  to this  subsection)  shall  be
released to the Purchaser.

     (f) With respect to any Mortgage Loan as to which the Purchaser has made an
Election to Delay  Foreclosure,  the related  Servicer shall continue to service
the Mortgage Loan in accordance  with its customary  procedures  (other than the
delay in  Commencement  of  Foreclosure  as  provided  herein).  If and when the
Purchaser shall notify the Company that it believes that it is appropriate to do
so, the related  Servicer may proceed with the  Commencement of Foreclosure.  In
any event,  if the Mortgage Loan is not brought  current by the mortgagor by the
time the loan becomes 6 months  delinquent,  the  Purchaser's  election shall no
longer be effective  and at the  Purchaser's  option,  either (i) the  Purchaser
shall  purchase  the Mortgage  Loan from the related  Trust Estate at a purchase
price equal to the fair market  value as shown on the Current  Appraisal,  to be
paid by (x) applying any balance in the Collateral Fund to such to such purchase
price, and (y) to the extent of any deficiency,  by wire transfer of immediately
available  funds from the  Purchaser  to the  Company for deposit in the related
Certificate  Account;  or (ii)  the  related  Servicer  shall  proceed  with the
Commencement of Foreclosure.

     (g) Upon the occurrence of a liquidation  with respect to any Mortgage Loan
as to which the Purchaser made an Election to Delay  Foreclosure and as to which
the  related  Servicer   proceeded  with  the  Commencement  of  Foreclosure  in
accordance with subsection (f) above, the Company shall calculate the amount, if
any, by which the value shown on the Current Appraisal obtained under subsection
(c) exceeds the actual sales price obtained for the related  Mortgaged  Property
(net of  Liquidation  Expenses  and  accrued  interest  related to the  extended
foreclosure  period),  and the Company shall  withdraw the amount of such excess
from the  Collateral  Fund,  shall remit the same to the Trust Estate and in its
capacity as Master  Servicer  shall apply such amount as additional  Liquidation
Proceeds  pursuant to the Pooling and  Servicing  Agreement.  After  making such
withdrawal,  all amounts  remaining  in the  Collateral  Fund in respect of such
Mortgage  Loan (after  adjustment  for all  permitted  withdrawals  and deposits
pursuant to this Agreement) shall be released to the Purchaser.

     Section 2.03 Purchaser's Election to Commence Foreclosure Proceedings

     (a) In  connection  with any  Mortgage  Loan  identified  in a report under
Section 2.01(a)(i)(B), the Purchaser may elect to instruct the Company to cause,
to the extent that the Company as Master  Servicer is granted such  authority in
the  related  Servicing  Agreement,  the related  Servicer  to proceed  with the
Commencement  of  Foreclosure  as soon as  practicable.  Such  election  must be
evidenced by written notice  received by the Company by 5:00 p.m., New York City
time,  on the third  Business  Day  following  the delivery of such report under
Section 2.01(a)(i).

     (b) Within two  Business  Days of making any  Election  to  Foreclose,  the
Purchaser  shall remit to the Company,  for deposit in the  Collateral  Fund, an
amount,  as  calculated  by the  Company,  equal to 125% of the  current  unpaid
principal balance of the Mortgage Loan and three months interest on the Mortgage
Loan at the  applicable  Mortgage  Interest  Rate. If and when any such Mortgage
Loan is brought current by the mortgagor,  all amounts in the Collateral Fund in
respect of such Mortgage Loan (after  adjustment  for all permitted  withdrawals
and deposits  pursuant to this Agreement)  shall be released to the Purchaser if
and to the extent that reimbursement therefor from amounts paid by the mortgagor
is not prohibited pursuant to the Pooling and Servicing Agreement or the related
Servicing  Agreement,  applicable law or the related mortgage note. The terms of
this  Agreement  will no longer apply to the servicing of any Mortgage Loan upon
the  failure of the  Purchaser  to deposit  the above  amounts  relating  to the
Mortgage Loan within two Business  Days of the Election to Foreclose  subject to
Section 3.01.

     (c) With respect to any Mortgage Loan as to which the Purchaser has made an
Election  to  Foreclose,  the  related  Servicer  shall  continue to service the
Mortgage  Loan  in  accordance  with  its  customary   procedures   (other  than
Commencement of Foreclosure as provided herein).  In connection  therewith,  the
Company shall have the same rights to make  withdrawals for Monthly Advances and
Liquidation  Expenses  from the  Collateral  Fund as are provided  under Section
2.02(e), and the Company shall make reimbursements thereto to the limited extent
provided under such subsection in accordance with its customary procedures.  The
Company shall not be required to cause, to the extent that the Company as Master
Servicer is granted  such  authority  in the related  Servicing  Agreement,  the
related Servicer to proceed with the Commencement of Foreclosure if (i) the same
is stayed as a result of the  mortgagor's  bankruptcy or is otherwise  barred by
applicable  law, or to the extent that all legal  conditions  precedent  thereto
have not yet been complied with, or (ii) the Company  believes there is a breach
of representations or warranties by the Company, a Servicer,  or a Seller, which
may result in a repurchase or  substitution  of such Mortgage Loan, or (iii) the
Company or related Servicer  reasonably  believes the Mortgaged  Property may be
contaminated with or affected by hazardous wastes or hazardous  substances (and,
without  limiting  the  related   Servicer's  right  not  to  proceed  with  the
Commencement of Foreclosure, the Company supplies the Purchaser with information
supporting  such  belief).  Any  foreclosure  that  has  been  initiated  may be
discontinued  (x) without  notice to the Purchaser if the Mortgage Loan has been
brought  current or if a refinancing  or  prepayment  occurs with respect to the
Mortgage Loan  (including by means of a short payoff  approved by the Purchaser)
or (y) with  notice to the  Purchaser  if the related  Servicer  has reached the
terms of a forbearance  agreement unless  instructed  otherwise by the Purchaser
within two Business Days of such  notification.  Any such  instruction  shall be
based upon a decision that such forbearance  agreement is not in conformity with
reasonable servicing practices.

     (d) Upon the occurrence of a liquidation  with respect to any Mortgage Loan
as to which the  Purchaser  made an  Election to  Foreclose  and as to which the
related  Servicer  proceeded with the  Commencement of Foreclosure in accordance
with subsection (c) above,  the Company shall  calculate the amount,  if any, by
which  the  unpaid  principal  balance  of the  Mortgage  Loan  at the  time  of
liquidation  (plus  all  unreimbursed   interest  and  servicing   advances  and
Liquidation  Expenses  in  connection  therewith  other than those paid from the
Collateral  Fund)  exceeds  the actual  sales  price  obtained  for the  related
Mortgaged  Property,  and the Company  shall  withdraw the amount of such excess
from the  Collateral  Fund,  shall remit the same to the Trust Estate and in its
capacity as Master  Servicer  shall apply such amount as additional  Liquidation
Proceeds  pursuant to the Pooling and  Servicing  Agreement.  After  making such
withdrawal,  all amounts  remaining in the Collateral Fund (after adjustment for
all  withdrawals  and  deposits  pursuant to  subsection  (c) in respect of such
Mortgage Loan shall be released to the Purchaser.

     Section 2.04 Termination

     (a) With respect to all Mortgage  Loans  included in the Trust Estate,  the
Purchaser's  right to make any Election to Delay  Foreclosure or any Election to
Foreclose and the Company's  obligations  under Section 2.01 shall terminate (i)
at such  time as the  Principal  Balance  of the Class B  Certificates  has been
reduced  to  zero,  (ii) if the  greater  of (x) 43% (or such  lower  or  higher
percentage  that  represents  the  related  Servicer's  actual  historical  loss
experience  with respect to the Mortgage Loans in the related pool as determined
by the Company) of the aggregate  principal  balance of all Mortgage  Loans that
are in  foreclosure or are more than 90 days  delinquent on a contractual  basis
and REO  properties  or (y) the  aggregate  amount  that the  Company  estimates
through the normal servicing  practices of the related Servicer will be required
to be withdrawn  from the  Collateral  Fund with respect to Mortgage Loans as to
which the Purchaser has made an Election to Delay  Foreclosure or an Election to
Foreclosure,  exceeds  (z) the  then-current  principal  balance  of the Class B
Certificates,  (iii) upon any transfer by the  Purchaser of any interest  (other
than the minority interest therein,  but only if the transferee provides written
acknowledgment  to the Company of the Purchaser's  right hereunder and that such
transferee will have no rights  hereunder) in the Class B Certificates  (whether
or not such transfer is registered  under the Pooling and Servicing  Agreement),
including any such transfer in connection with a termination of the Trust Estate
or (iv) upon any breach of the terms of this Agreement by the Purchaser.

     (b)  Except as set forth in  2.04(a),  this  Agreement  and the  respective
rights,  obligations  and  responsibilities  of the  Purchaser  and the  Company
hereunder shall  terminate upon the later to occur of (i) the final  liquidation
of the last Mortgage  Loan as to which the Purchaser  made any Election to Delay
Foreclosure  or any Election to Foreclose  and the  withdrawal  of all remaining
amounts in the  Collateral  Fund as provided  herein and (ii) ten Business Days'
notice.  The Purchaser's  right to make an election  pursuant to Section 2.02 or
Section 2.03 hereof with respect to a particular  Mortgage Loan shall  terminate
if the Purchaser fails to make any deposit required  pursuant to Section 2.02(d)
or 2.03(b) or if the Purchaser fails to make any other deposit to the Collateral
Fund pursuant to this Agreement.

interest  granted  hereunder  for the benefit of the  Certificateholders,  until
withdrawn from the Collateral Fund pursuant to Section 2.02 or 2.03 hereof.  The
Collateral  Fund shall be an "outside  reserve  fund"  within the meaning of the

Fund shall be that of the Purchaser.  All  distributions  from the Trust Fund to
the  Collateral  Fund shall be treated as  distributed  to the  Purchaser as the
beneficial owner thereof.

the  event the  Purchaser  has made any  Election  to Delay  Foreclosure  or any
Election to Foreclose, prior to any distribution to the Purchaser of all amounts
remaining in the Collateral  Fund, funds in the Collateral Fund shall be applied
consistent with the terms of this Agreement.

     Section 3.02. Collateral Fund Permitted Investments.

     The Company shall,  at the written  direction of the Purchaser,  invest the
funds in the  Collateral  Fund in Collateral  Fund Permitted  Investments.  Such
direction shall not be changed more frequently than quarterly. In the absence of
any direction,  the Company shall select such investments in accordance with the
definition of Collateral Fund Permitted Investments in its discretion.

     All income and gain  realized  from any  investment as well as any interest
earned  on  deposits  in  the  Collateral  Fund  (net  of  any  losses  on  such
investments)  and any  payments of principal  made in respect of any  Collateral
Fund  Permitted  Investment  shall be  deposited  in the  Collateral  Fund  upon
receipt.  All costs and realized losses associated with the purchase and sale of
Collateral  Fund Permitted  Investments  shall be borne by the Purchaser and the
amount  of net  realized  losses  shall be  deposited  by the  Purchaser  in the
Collateral Fund promptly upon realization.  The Company shall  periodically (but
not more  frequently  than monthly)  distribute to the Purchaser upon request an
amount of cash,  to the extent cash is  available  therefore  in the  Collateral
Fund,  equal to the amount by which the balance of the  Collateral  Fund,  after
giving effect to all other  distributions to be made from the Collateral Fund on
such  date,  exceeds  the  Required  Collateral  Fund  Balance.  Any  amounts so
distributed  shall be  released  from the lien  and  security  interest  of this
Agreement.

     Section 3.03. Grant of Security Interest

     The  Purchaser  hereby  grants  to  the  Company  for  the  benefit  of the
Certificateholders under the Pooling and Servicing Agreement a security interest
in and lien on all of the  Purchaser's  right,  title and interest,  whether now
owned or hereafter acquired, in and to: (1) the Collateral Fund, (2) all amounts
deposited in the Collateral  Fund and Collateral  Fund Permitted  Investments in
which such  amounts are  invested  (and the  distributions  and proceeds of such
investments)  and (3) all cash and  non-cash  proceeds of any of the  foregoing,
including  proceeds of the  voluntary  conversion  thereof (all of the foregoing
collectively, the "Collateral").

     The  Purchaser  acknowledges  the lien on and the security  interest in the
Collateral for the benefit of the  Certificateholders.  The Purchaser shall take
all actions  requested by the Company as may be reasonably  necessary to perfect
the security  interest  created under this Agreement in the Collateral and cause
it to be  prior  to all  other  security  interests  and  liens,  including  the
execution  and  delivery  to the  Company  for filing of  appropriate  financing
statements in accordance with applicable law. The Company shall file appropriate
continuation  statements,  or  appoint  an  agent  on its  behalf  to file  such
statements, in accordance with applicable law.

     Section 3.04. Collateral Shortfalls.

     In the event that amounts on deposit in the Collateral Fund at any time are
insufficient  to  cover  any  withdrawals  therefrom  that the  Company  is then
entitled to make hereunder, the Purchaser shall be obligated to pay such amounts
to the Company  immediately  upon demand.  Such  obligation  shall  constitute a
general corporate  obligation of the Purchaser.  The failure to pay such amounts
within two Business Days of such demand (except for amounts to cover interest on
a Mortgage  Loan  pursuant  to Sections  2.02(d)  and 2.03 (b)),  shall cause an
immediate  termination  of the  Purchaser's  right to make any Election to Delay
Foreclosure  or Election to Foreclose and the Company's  obligations  under this
Agreement  with  respect to all  Mortgage  Loans to which  such  insufficiencies
relate, without the necessity of any further notice or demand on the part of the
Company.
